java.lang.Object com.esri.arcgis.location.RouteEventSource
public class RouteEventSource
Route event source object.
A RouteEventSource serves an event table as a dynamic feature class. Every row in the table is served as a feature whose shape is calculated on the fly, every time it is asked for. This is Dynamic Segmentation.
Because a RouteEventSource is a subclass of a FeatureClass, you can use it for things like being the basis of a FeatureLayer in ArcMap.
A RouteEventSource is created by its name object counterpart, RouteEventSourceName.

IDataset::Category returns a description of the category of the dataset. The description returned from the Category property is the same value that is displayed in the Type column within the Contents tab in ArcCatalog. The value will contain a description of the dataset such as "Topology" prefixed with a description of the type of workspace containing the dataset such as "File Geodatabase".
The description returned from IDataset::Category may change between releases of ArcGIS. In addition to this, returned strings are localized, meaning that code relying on a specific string being provided may fail when deployed with a different version of ArcGIS than it was developed with, or when deployed to a client using a different language than it was developed with.

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.
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.

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.

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:
// Get a recycling cursor for the OID array.
int[] oids = new int[] { 10844, 10853, 10871 };
ICursor cursor = table.getRows(oids, true);

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.

This method will edit the rows matching the query filter's constraints. The values in each row will be replaced with the corresponding field's value in the provided row buffer. The fields being edited should be specified in the query filter's SubFields property. If the row buffer contains null values, and the SubFields property is not properly set, the row's values will be overwritten with the row buffer's null values.

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.

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.
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.

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.

Each feature class or table registered with the geodatabase is an object class. Object classes have a unique ID which distinguishes them from other object classes in the geodatabase. The ObjectClassID property returns this ID as a long. The object class ID is assigned by the system when the class is created, or registered with the geodatabase, it cannot be modified.
Those feature classes and tables that are in the database, but not registered with the geodatabase will always have an object class ID of -1.

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

- If the ArcObject component throws an exception.public boolean canBypassStoreMethod() throws IOException, AutomationException
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.

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.

- If the ArcObject component throws an exception.public IFeature createFeature() throws IOException, AutomationException
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

public IFeatureCursor search(IQueryFilter filter, boolean recycling) throws IOException, AutomationException
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.

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.
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.
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.
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.
