getExtent

public IEnvelope getExtent()
                    throws IOException,
                           AutomationException

The extent of the GeoDataset.

Remarks

The IGeoDataset::Extent property returns an envelope representing the maximum extent of data which has been stored in the dataset.

Consider the following scenario. A new feature class has features added to it. The IGeoDataset::Extent is then requested and an envelope is returned. The extents of the envelope returned are represented by the red box in the image below.

The red box represents the IGeoDataset extent

If a portion of the features were then deleted and the extent is again requested an envelope with the exact same extents as during the first request would be returned (see image below). This is because the deletion of features does not shrink the extent. However all additions of features outside the red box would increase the envelope returned to encompass the newly added features.

The red box represents the IGeoDataset extent after some of the features have been deleted

If you would like to update the IGeoDataset::Extent property to reflect the current features in your dataset please see IFeatureClassManage::UpdateExtent (also see IFeatureClassLoad). In the image below the extent has been updated and a new envelope is being returned.

The red box represents the IGeoDataset extent after it has been updated

ESRI's GroupLayer implements this property differently from most other layer coclasses. When you instantiate a new GroupLayer, this property will return a valid envelope with zero height and width. With most other newly instantiated layers (for example FeatureLayer, RasterLayer, TinLayer), this property initally returns Nothing.

                                   AutomationException

The set of properties for the dataset.

Description

The PropertySet property is used to return any additional intrinsic properties (but not metadata properties) that may apply to the dataset. One use of this property is to distinguish between the types of File Geodatabase datafile formats. If called on a Feature Class or Table in a File Geodatabase the Datafile Format property can either be esriFGDBStandardDatafile or esriFGDBCompressedDatafile.

Most datasets do not implement this property and will either raise an error or return a null value if it's called. There are a handful of exceptions that will return property sets; these include the datasets from file geodatabases (as mentioned above) and coverages.

Remarks

Examples of intrinsic properties for which explicit methods exist include the SpatialReference and the Extent methods available on the IGeoDataset interface. In most cases this PropertySet will be empty.

IDataset::PropertySet is not supported for Graph objects such as a Geometric Network.

Creates a row in the database with a system assigned object ID and null property values.

Remarks

The CreateRow method creates a new row in the underlying database with a system assigned object id value. A row object representing the created row is returned to the caller. The row object returned has the system assigned object ID as the value of the OIDField. All other fields are initialized to null values if they can be made null and to built-in default values appropriate to the type of the field if they cannot be made null.

The caller is responsible for setting the desired field values into the row and calling the Store method on the row. If the table represents an object class with subtypes, then it is the caller�s responsibility to set the default subtype code into the row and call the InitDefaultValues method on the row before storing, if that is the desired result. For tables without object behavior, insert cursors offer a more efficient way for inserting new rows.

public IRow getRow(int oID)
            throws IOException,
                   AutomationException

The row from the database with the specified object ID.

Remarks

The GetRow method returns an existing row object, given its object ID value. The caller can query the returned row object for additional object specific interfaces. The retrieved row may be modified; calling Store on the row object after changing it will trigger messages to related objects and will mark the row for committing to the database.

Supported Platforms

Windows, Solaris, Linux

Specified by:: getRow in interface ITable

Parameters:: oID - The oID (in)
Returns:: A reference to a com.esri.arcgis.geodatabase.IRow
Throws:: IOException - If there are interop problems.; AutomationException - If the ArcObject component throws an exception.

getRows

public ICursor getRows(Object oids,
                       boolean recycling)
                throws IOException,
                       AutomationException

The cursor of rows based on a set of object ids.

Remarks

The GetRows method returns a cursor that may be used to retrieve a set of rows specified by the input array of object id values. See the description of the Search method to understand the meaning of the recycling parameter. It is far more efficient to retrieve a set of rows using the GetRows method than it is to retrieve each individual row using the GetRow method. The retrieved rows may be modified; Store should be called on the row objects after changing them.

The oids parameter should be passed an integer array. For example:

                                  AutomationException

Creates a row buffer that can be used with an insert cursor.

Remarks

The CreateRowBuffer method creates a new row buffer object in memory and returns it to the caller. No row is created in the database. The returned row buffer does not have an object ID value. The caller can set values into the row buffer and use it as an argument to the InsertRow method on an insert cursor; the latter is obtained by calling the Insert method on the Table.

update

public ICursor update(IQueryFilter queryFilter,
                      boolean recycling)
               throws IOException,
                      AutomationException

Returns a cursor that can be used to update Rows selected by the specified query.

Remarks

The Update method returns an update cursor that can be used to update or delete rows. It offers somewhat faster performance than multiple calls to Store or Delete on row objects fetched using a non-recycling search cursor for tables storing simple rows and simple features. There is no difference in performance for complex objects and features.

When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:: update in interface ITable

Parameters:: queryFilter - A reference to a com.esri.arcgis.geodatabase.IQueryFilter (in); recycling - The recycling (in)
Returns:: A reference to a com.esri.arcgis.geodatabase.ICursor
Throws:: IOException - If there are interop problems.; AutomationException - If the ArcObject component throws an exception.

insert

public ICursor insert(boolean useBuffering)
               throws IOException,
                      AutomationException

Returns a cursor that can be used to insert new Rows.

Remarks

The Insert method returns an insert cursor that can be used to bulk insert rows. It offers significantly faster performance than multiple calls to CreateRow and Store for tables storing simple rows and simple features (that is, for tables whose CLSID is esriGeoDatabase.Row, esriGeoDatabase.Object, or esriGeoDatabase.Feature).

Insert cursors on tables containing complex objects use the CreateRow and Store methods to achieve polymorphism, and there is no difference in performance in these cases.

                            IWorkspace selectionContainer)
                     throws IOException,
                            AutomationException

A selection that contains the object ids selected by the specified query.

Remarks

The Select method returns a selection set that holds either row IDs or row objects from the Table depending on the selection option. Multiple selection sets can be created on the same table. It is up to a client application or object to keep a reference on created selections and use them as appropriate. For example, a FeatureLayer creates and uses selections on a FeatureClass (a type of Table).

The selType parameter determines the type of selection set that will be created: an ID set, a snapshot, or a hybrid. See the ISelectionSet interface for a comparison of the three types.

When calling Select the selectionContainer parameter is no longer required. A null value should be passed as this parameter.

The alias name of the object class.

Description

Returns the alias name for the object class.

Remarks

Object classes in a geodatabase can have between one and three names. The name of the object class, which is the same as the name of the table in the DBMS in which the objects in the object class are stored, the alias name which the user can set for display purposes in end user applications. The third name is the model name which is a tool for developers of custom objects to use to guarantee the names of objects independent of the true name or alias name.

The AliasName property returns the alias name for the object class. If the object class has no alias name, then AliasName will return the name of the object class (fully qualified if on ArcSDE). The alias name can be modified using the IClassSchemEdit interface.

canBypassStoreMethod

public boolean canBypassStoreMethod()
                             throws IOException,
                                    AutomationException

Indicates if updates to objects can bypass the Store method and OnChange notifications for efficiency.

Remarks

CanBypassStoreMethod is a convenience method that returns True if the instances of this object class have no custom behavior associated with creating or updating objects and if the object class does not participate in composite relationship classes or in relationship classes that require object notification. A return value of True implies that insert cursors handed out by the geodatabase will internally bypass the CreateRow and Store mechanisms when creating objects. A return value of False indicates that insert cursors will not bypass custom Store or OnChanged behavior implemented by the custom row object for this class.

By default, this method returns False for custom object classes. The developer of a custom object class can change this behavior by implementing this interface on the class extension associated with the class and returning True for the method.

In addition, a developer can implement this interface on the class extension of a simple class and set this property to False . Doing this will ensure that when features in the class are inserted, updated or deleted by editor tools that use insert and update cursors, such as Planarize, Create Features and the Object Loader do not bypass Store or OnChanged behavior. By default, this property for a simple class is logically True, meaning these tools will not broacast Geodatabase events which in turn are not rebroadcast as editor events (for which a custom editor application may be listening). Set this to False for those classes for which you always want to have these events broadcast. Alternatively, this can be set globally for the entire edit session using the IWorkspaceEditControl interface.

                                    AutomationException

Indicates if updates to objects can be safely made outside of an edit session.

Remarks

CanBypassEditSession is a convenience method that returns True if the instances of this object class may be created or updated outside of a Geodatabase edit session (an edit session is started by using the StartEditing method on the IWorkspaceEdit or the StartMultiuserEditing method on the IMultiuserWorkspaceEdit interface).

If True , then applications may update the data in this object class using any of the data updating interfaces and methods described here without starting an edit session. In this case applications are responsible for starting host database transactions as appropriate and for discarding cached object states across transaction boundaries when running on an ArcSDE database.

If False, then applications should always make modifications to the data in this object class within an edit session for correct multi-user behavior and for correct management of database state internally cached by the Geodatabase for the objects in this object class.

This method returns False for network feature classes. By default, this method returns True for non-network custom object classes. The developer of a non-network custom object class can change this behavior by implementing this interface on the class extension associated with the class and returning true for the method.

                                AutomationException

The subtypes associated with the class.

Description

Subtypes returns a IEnumSubtype populated with all of the subtypes for the given object class.

Remarks

Every ObjectClass has a default subtype code. If the user has not explicitly specified a default subtype or a subtype field, then DefaultSubtypeCode will return a subtype code of zero. Additionally, you can query the HasSubtype property; a value of False indicates an absence of a default subtype code, True indicates the presence of a default subtype code.

If the client instead asks for the enumeration of subtypes associated with an ObjectClass and no subtype has been previously added to the ObjectClass, then the enumerator will contain a single entry with a code of zero. The subtype field index value will be �1 if a default subtype has not been previously specified. Subtypes may only be short or long integers (esriFieldTypeSmallInteger or esriFieldTypeInteger). When setting the default subtype code, if one already exists, then it will be deleted. A subtype field must have been specified prior to setting the subtype code value.

Every type of field, except for esriFieldTypeShape, may have a default value. When setting the default value (which my be assigned on a subtype basis), it will be checked against the field�s associated Domain (if one exists) for validity.

This property returns all of the subtypes for the associated object class. Subtypes returns an IEnumSubtype enumeration which you can loop through to get all of the subtypes.

                        AutomationException

The type of the default Shape for the features in this feature class.

Description

ShapeType returns the basic type of geometry of a shape. For the purposes of using the ShapeType property in deciding how to render/symbolize a layer, only esriGeometryPolyline, esriGeometryPolygon, esriGeometryPoint, esriGeometryMulitpoint, and esriGeometryMultipatch need to be checked. All the other types will report as being one of these five types. The reason is that esriGeometryBezier3Curve or esriGeometryPath, etc. can be segments or parts of another shape.

createFeature

public IFeature createFeature()
                       throws IOException,
                              AutomationException

Create a new feature, with a system assigned object ID and null property values.

Remarks

CreateFeature will create a new feature for the feature class. The new feature is by default assigned a unique object ID (OID). All other fields are initialized to null values if they can be made null and to built-in default values appropriate to the type of the field if they cannot be made null. Use the IFeature::Store method to actually store this new feature in the database. When working with a versioned feature class, CreateFeature should only be called within an edit session. You can start an edit session by calling IWorkspaceEdit::StartEditing. All edits to features that participate in a Topology or Geometric Network must be performed within an edit session and bracketed within an edit operation.

After calling CreateFeature, the default subtype value is not automatically set nor are default values initialized. For features without a subtype that have defined default values, calling IRowSubtypes::InitDefaultValues will initialize the default values. Use IRowSubtypes::SubtypeCode to set the subtype value for features with subtypes before calling IRowSubtypes::InitDefaultValues to initialize the default values for the particular subtype.

Calling the CreateFeature method on a feature class (via the IFeatureClass interface on the feature class) has the same effect as calling the CreateRow method on the FeatureClass (via the ITable interface on the feature class) except that the IFeatureClass methods return IFeature interfaces on the returned row object.

If multiple features with common attributes are being sequentially created, the CreateFeatureBuffer method, IFeatureCursor.InsertFeature method and IFeatureBuffer interface should be used for better performance.

The basic process to create a new feature is:

1) Create the feature
2) Create the geometry for the feature
3) Store the geometry in the feature
4) Store the feature

Get the feature with the specified object ID.

Remarks

GetFeature will return a feature from the feature class with the parameter-specified Object ID (OID). This method is typically used to find a particular feature with a known Object ID. A cursor should be used to iterate through all features in a feature class.

Calling the GetFeature method on a feature class (via the IFeatureClass interface on the feature class) has the same effect as calling the GetRow method on the feature class (via the ITable interface) except that the return value is an IFeature reference, rather than IRow.

Deprecated. This method uses C style arrays which are not supported in the ArcGIS API for Java. It is replaced by GeoDatabaseHelper#getFeatures(com.esri.arcgis.geodatabase.IFeatureClass, int[], boolean).

Get a cursor of Rows given a set of object ids.

Remarks

GetFeatures will return an IFeatureCursor which contains the features from the feature class with the parameter-specified Object IDs (OID). This method can be used to loop through a particular set of features with known Object IDs.

Calling the GetFeatures method from the IFeatureClass interface has the same effect as calling the GetRows method from the ITable interface except that the return value is an IFeatureCursor reference, rather than an ICursor reference.

The fids parameter should be provided with an integer array. If the array contains an invalid Object ID, no error will occur, and no feature will be retrieved for the value.

This method should not be called from .NET or Java applications. Instead, call IGeoDatabaseBridge.GetFeatures.

The unique ID for the Feature Class.

Remarks

This read-only property will return the unique identifier for this feature class. All feature classes inside Geodatabases have a unique ID. Coverage and Shapefile feature classes do not, so IFeatureClass::FeatureClassID will always return -1 for Coverage and Shapefile feature classes. Since IFeatureClass inherits from IObjectClass, you can also get the feature class ID from IObjectClass:: ObjectClassID.

                                          AutomationException

Create a feature buffer that can be used with an insert cursor.

Remarks

The CreateFeatureBuffer method creates a feature buffer and returns the IFeatureBuffer interface. This can be used to create new features in the feature class with an insert cursor. Like creating a feature with IFeatureClass::CreateFeature, the field values for the new feature must be initialized to some value before it can be stored in the database. All edits to features that participate in a Topology or Geometric Network must be performed within an edit session and bracketed within an edit operation.

Calling the CreateFeatureBuffer method in IFeatureClass has the same effect as calling the CreateRowBuffer interface in ITable except that the IFeatureClass methods return an IFeatureBuffer interface on the created row buffer.

search

                      throws IOException,
                             AutomationException

Returns an object cursor that can be used to fetch feature objects selected by the specified query.

Remarks

Search will return an IFeatureCursor with all of the features that satisfy the attribute and/or spatial constraints as specified by an IQueryFilter reference. If a null value is passed to the filter parameter, the feature cursor will return all of the features from the feature class.

The recycling parameter controls row object allocation behavior. Recycling cursors rehydrate a single feature object on each fetch and can be used to optimize read-only access, for example, when drawing. It is illegal to maintain a reference on a feature object returned by a recycling cursor across multiple calls to NextFeature on the cursor. Features returned by a recycling cursor should not be modified. Non-recycling cursors return a separate feature object on each fetch. The features returned by a non-recycling cursor may be modified and stored with polymorphic behavior.

The Geodatabase guarantees "unique instance semantics" on non-recycling feature objects fetched during an edit session. In other words, if the feature retrieved by a search cursor has already been instantiated and is being referenced by the calling application, then a reference to the existing feature object is returned.

Non-recycling feature cursors returned from the Search method *MUST* be used when copying features from the cursor into an insert cursor of another class. This is because a recycling cursor reuses the same geometry and under some circumstances all of the features inserted into the insert cursor may have the same geometry. Using a non-recycling cursor ensures that each geometry is unique.

Existing rows can be edited with either a search cursor or an update cursor. When using a search cursor, NextRow is called, returning a reference to a row. The row is edited, and IRow.Store is called. When using an update cursor, NextRow is called, the row is edited, and ICursor.UpdateRow is called with the row as a parameter. It is important to remember, when using an update cursor, do not call the Store method.

In the same way, rows can be deleted using a search cursor or an update cursor, with IRow.Delete used instead of IRow.Store, and ICursor.DeleteRow used instead of ICursor.UpdateRow.

The recommended approach depends on whether or not the edits are being made in an edit session, if the cursor is being used by ArcMap or by an Engine application, and if the features being edited are simple or complex. The table below shows which approach to use in different situations:

	ArcMap	Engine - Simple	Engine - Complex
Inside edit sessions	Search Cursor	Search Cursor	Search Cursor
Outside edit sessions	Search Cursor	Update Cursor	Search Cursor

A search cursor is always recommended in ArcMap, because the query may be satisfied by the contents of the map cache, making a DBMS query unnecessary.

When working with simple features and edit sessions in an Engine application, it's recommended that a search cursor be used to take advantage of batched updates in edit operations. With complex features, on the other hand, update calls are overridden by the features' custom behavior, meaning that the feature's store method will be called even if an update cursor is used.

synchronize

public void synchronize(int action,
                        int interval)
                 throws IOException,
                        AutomationException

Updates metadata with the current properties; may create metadata if it doesn't already exist.

Description

The Synchronize method is used to extract metadata properties from an object and write those properties to the metadata .xml. Depending on the value of the esriMetaSyncAction, the Synchronize method may generate a new set of metadata if it doesn't already exist.

Remarks

The following actions will result in synchronization given each of the listed conditions:

Action	Metadata status	Esri/Sync element	Interval parameter
esriMSAAccessed	Doesn't matter	Must not be FALSE	Must be less than actual interval
esriMSAAlways	Doesn't matter	Doesn't matter	Doesn't matter
esriMSACreated	Must not exist	Must not be FALSE	Must be less than actual interval
esriMSANotCreated	Must exist	Must not be FALSE	Must be less than actual interval
esriMSAOverwrite	Doesn't matter	Doesn't matter	Doesn't matter

The difference between esriMSAAlways and esriMSAOverwrite lies in which elements are synchronized. esriMSAAlways will honor the removal or value change of an element's Sync attribute (to disable synchronization), whereas using esriMSAOverwrite is equivalent to setting the IXmlPropertySet2.OverwriteSyncAttribute to true for the metadata's property set, meaning that even elements without a Sync attribute of TRUE will be synchronized.

changeSchemaLock

public void changeSchemaLock(int schemaLock)
                      throws IOException,
                             AutomationException

Changes a schema lock.

Remarks

There are two kinds of schema locks: shared and exclusive. Shared schema locks are applied automatically by the geodatabase when accessing a dataset and are removed when all references to the dataset are removed. For this reason, it's not necessary to explicitly apply or remove shared schema locks. There is no limit to the number of shared schema locks a dataset or object can have at any given time.

In contrast to shared schema locks, exclusive schema locks are controlled by the developer or ArcGIS application, such as ArcMap or ArcCatalog. An exclusive lock is used to lock a geodatabase dataset or object from use by others to make the necessary changes to it. An exclusive lock is promoted from a shared lock and demoted back to a shared lock when no longer needed. The presence of additional shared schema locks on a dataset or object prevents an exclusive schema lock from being applied and precludes the ability to make changes to the underlying dataset and its schema while it is in use. Only one exclusive schema lock is allowed per dataset. As opposed to shared schema locks, exclusive schema locks are not applied or removed automatically; it is the responsibility of the developer to apply or remove exclusive schema locks.

Limit the scope of exclusive schema locks to the operation that requires the lock. Gather the necessary information to perform the action, obtain the exclusive lock, make the change, and release the lock. Some examples of operations for which an exclusive schema lock should be obtained include:

Modifications to attribute domains, such as adding or removing values from a coded value domain or changing the range for range domains

Adding or deleting a field from a feature class or object class
Associating a class extension with a feature class
Creating a topology, geometric network, network dataset, terrain, schematic dataset, representation, or cadastral fabric on a set of feature classes
Any use of the IClassSchemaEdit interface
Putting a feature class into and taking it out of load-only mode with the IFeatureClassLoad.LoadOnlyMode method
Managing (creating, deleting, or modifying) spatial and attribute indexes

Once the action requiring an exclusive schema lock is complete, the exclusive schema lock must be demoted to a shared lock. This includes when errors are raised during the schema modification, for example, consider the case where a field is being deleted from a feature class. To delete the field, an exclusive schema lock is obtained. However, on the call to DeleteField, an error is thrown; that is, the field being deleted is a required field, such as the ObjectID field. In the handling of the error, the exclusive schema lock must be demoted to a shared lock before proceeding.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:: changeSchemaLock in interface ISchemaLock

Parameters:: schemaLock - A com.esri.arcgis.geodatabase.esriSchemaLock constant (in)

getCurrentSchemaLocks

public void getCurrentSchemaLocks(IEnumSchemaLockInfo[] schemaLockInfo)

                                  AutomationException

The list of current locks.

Remarks

The ISchemaLockInfo interface is used in concert with ISchemaLock to provide information about a schema lock, for example, whether it is shared or exclusive and for ArcSDE geodatabases, the name of the user who has the lock. Note that there will always be at least one schema lock on the dataset. Also note that by checking the schema locks on a dataset a shared schema lock is applied to the data.
