public class Topology
Esri Topology object.
A Topology is a collection of simple feature classes within the same feature dataset that participate in topological relationships with a set of rules that govern those relationships. The Topology object is not cocreateable, topologies must be created through another method call, ITopologyContainer::CreateTopology.
Topologies support the IFeatureClassContainer interface that can be used to return the feature classes participating in the topology. Among other interfaces, Topologies also support IDataset.
Each topology has one inherent rule, esriTRTFeatureLargerThanClusterTolerance, which identified features that are less than the defined cluster tolerance for the topology.

public String getCategory()
throws IOException,
AutomationException
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.

public IPropertySet getPropertySet()
throws IOException,
AutomationException
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.
getPropertySet in interface IDatasetIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public boolean canCopy()
throws IOException,
AutomationException
The CanCopy, CanDelete, and CanRename properties are meant to be used in conjunction with the Copy, Delete, and Rename methods and signify whether a dataset is supported by these methods. For example, you may not delete a network feature class nor can you use the Copy method on a Geodatabase feature class. To copy Geodatabase datasets, including feature classes, geometric networks, topologies, etc., use the IGeoDBDataTransfer interface.
The CanCopy method is supported by:

public boolean canRename()
throws IOException,
AutomationException
The CanCopy, CanDelete, and CanRename properties are meant to be used in conjunction with the Copy, Delete, and Rename methods and signify whether a dataset is supported by these methods. For example, you may not delete or rename a network feature class nor can you use the Copy method on a Geodatabase feature class. To copy Geodatabase datasets, including feature classes, geometric networks, topologies, etc., use the IGeoDBDataTransfer interface.
canRename in interface IDatasetIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public void rename(String name)
throws IOException,
AutomationException
IDataset::Rename does not support the renaming of Graph objects such as a Geometric Network. In addition, certain feature classes, such as network feature classes, cannot be renamed.
rename in interface IDatasetname - The name (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public boolean isBeingEdited()
throws IOException,
AutomationException
Once an edit session has been started on a workspace, the IsBeingEdited method on the IDatasetEdit interface can be used to determine if a particular dataset is participating in the edit session.
The reasons why a dataset may not participate include the connected user has no privileges or permission to edit the dataset, the connected user is not licensed to edit this type of dataset, or the dataset is not versioned but a versioned edit session has been started (or vice versa).
isBeingEdited in interface IDatasetEditIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ISpatialReference getSpatialReference()
throws IOException,
AutomationException
This property is read only. For layers, when the first layer is added to ArcMap, its spatial reference is read by this property, and the map is set to this spatial reference.
Instances of the esriCarto.GroupLayer class will return null for this property, as a group layer can contain multiple datasets with different spatial references.
Modifications to a spatial reference returned by this property will not be persisted. To modify the spatial reference of a dataset, the IGeoDatasetSchemaEdit and IGeoDatasetSchemaEdit2 interfaces should be used.
getSpatialReference in interface IGeoDatasetgetSpatialReference in interface ITopologyPropertiesIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IEnvelope getExtent()
throws IOException,
AutomationException
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. With most other newly instantiated layers (for example FeatureLayer, RasterLayer, TinLayer), this property initally returns Nothing.

public void getCurrentSchemaLocks(IEnumSchemaLockInfo[] schemaLockInfo)
throws IOException,
AutomationException
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.

getClasses in interface IFeatureClassContainergetClasses in interface ITopologyPropertiesIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public double getZClusterTolerance()
throws IOException,
AutomationException
The ZClusterTolerance property returns the Z cluster tolerance that was specified when the topology was built. As with the cluster tolerance, the Z cluster tolerance of the topology cannot be changed. In order to modify the Z cluster tolerance, the topology must be deleted and rebuilt with the new ZClusterTolerance value.
Unlike the cluster tolerance property, the ZClusterTolerance value indicates cluster tolerance distance as well as the Z clustering model that applies to the topology. A ZClusterTolerance value of 0 signifies the Building model, Z values of coincident vertices are not changed. A ZClusterTolerance value greater than 0 signifies the Terrain model, Z values of coincident vertices that are within the Z clsuter tolerance will be averaged together, based on the ZRank assigned to the features. (see ITopologyClass::ZRank )
ZClusterTolerance will return a value of -1 for any topology:
getZClusterTolerance in interface ITopology2IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public int getState()
throws IOException,
AutomationException
The State property indicates the current status of the Topology; whether the topology has been validated and if so, whether any topology errors have been discovered.
getState in interface ITopologyIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IEnvelope validateTopology(IEnvelope areaToValidate)
throws IOException,
AutomationException
ValidateTopology validates the topology in the area specified by the areaToValidate envelope and returns the envelope of the validated area . If an empty envelope is supplied, ValidateTopology will return an empty validated area. If an envelope is supplied which does not intersect or contain a dirty area, an empty envelope is returned.
Before validating a given area, use a polygon object to verify a Dirty Area is present at the given location. This can be done using the ITopology::DirtyArea property. The envelope of the polygon can then be passed into ValidateTopology.
ValidateTopology can be performed outside of an edit session on Topologies within Personal or File Geodatabases or on Topologies within ArcSDE Geodatabases which have not been registered as versioned. Once the Topology is registered as versioned, ValidateTopology must be performed within an edit session. When performed within an edit session, ValidateTopology must also be bracketed within an edit operation.
It is not necessary to validate the entire dirty area of the topology. Subsets of the dirty area can be specified, resulting in a partial validation. When a partial validation occurs, the original dirty area is clipped by the envelope that was supplied for the validation.
ValidateTopology validates the dirty area of the topology in the area specified by the areaToValidate envelope. The validate process evaluates all the rules and produces any topology errors corresponding to areas in which a rule has been violated. The ValidateTopology function returns the envelope of the validated area. If an empty envelope is supplied, ValidateTopology will return an empty validated area. ValidateTopology can be performed outside of an edit session on topologies within Personal Geodatabases or on topologies within ArcSDE Geodatabases that have not been registered as versioned. Once a topology is registered as versioned, ValidateTopology must be performed within an edit session and bracketed within an edit operation. The IWorkspaceEdit or IEditor interfaces can be used to manage edit sessions and edit operations.
An entire topology can be validated by supplying the envelope of the extent of the topology.
By supplying a polygon object to the ITopology::DirtyArea property, the dirty area at a particular location can be returned. The envelope of the returned dirty area polygon can then be passed into ValidateTopology.
The OnCreate, OnDelete or OnChange events are not fired during a Topology Validation. The OnCreate and OnDelete events are not applicable since a Validate does not create or delete features. The OnChange event is not fired for performance reasons as a large number of features may be changed during a Validate. In addition, features may be changed many times.

AutomationException - If the ArcObject component throws an exception.
public ITopologyGraph getCache()
throws IOException,
AutomationException
The Cache property returns a reference to the topology graph of the Topology. The topology graph can be used for working with topological primitives such as edges and nodes. For more information, see the TopologyGraph object for additional help.

public void addClass(IClass classToAdd,
double weight,
int xYRank,
int zRank,
boolean eventNotificationOnValidate)
throws IOException,
AutomationException
The AddClass method is used to add a feature class to the topology, with the specified weight and ranks. The Weight must be an integer between 1 and 10. Although it is not used in ArcGIS, it must still be specified. The XY and Z Rank must each be an integer between 1 and 63 (Ranks higher than 51 are will result in errors when specified in either the New Topology wizard or Topology property page). Even if the feature class being added to the topology is not Z aware, it must have a Z rank specified. The XY and Z ranks represent the accuracies of the feature class, relative to other feature classes participating in the topology. Feature classes with a higher rank, such as 1 are more accurate than feature classes with a lower rank, such as 2. Ranks are a relative measure of accuracy; the difference between two features classes of ranks 1 and 2 is the same as two feature classes with ranks of 1 and 50. Multiple feature classes in topology can have the same rank.
The EventNotificationOnValidate parameter indicates if an event is broadcast when the Topology that the feature class participates in, is validated. The EventNotificationOnValidate property can only be set if the Topology is created programmatically. Feature classes added to a topology using the New Topology wizard in ArcCatalog, will have a value of False for EventNotificationOnValidate.
Non-simple feature classes, such as annotation, dimension, geometric network feature classes and feature classes already in a topology cannot be added to a Topology. Object classes or tables and versioned simple feature classes, cannot be added to a Topology. After a populated feature class is added to a topology that has been validated, in whole or in part, the state of the topology will be changed and a dirty area corresponding to the extent of the feature class will be created. If an unpopulated feature class is added to a topology, the topology's state will not change and no dirty area will be created. The AddClass method cannot be called on versioned topologies in SDE, but can be called on non-versioned topologies in SDE and topologies in a file or personal geodatabase.

public int getMaximumGeneratedErrorCount()
throws IOException,
AutomationException
Each topology has a maximum number of errors that can be generated on Validate, which can be determined through the MaximumGeneratedErrorCount property. MaximumGeneratedErrorCount can only be specified when a Topology is created programmatically. All topologies created with the New Topology wizard in ArcCatalog have a MaximumGeneratedErrorCount of –1, indicating no limit to the number of errors that can be generated. As with the ClusterTolerance, the MaximumGeneratedErrorCount property cannot be changed, a topology must be deleted and rebuilt in order to specify a new value.

public void promoteToRuleException(ITopologyErrorFeature errorException)
throws IOException,
AutomationException
The PromoteToRuleException method will promote the specified error to an exception feature. On a topology in an ArcSDE geodatabase, PromoteToRuleException, must be called from within an edit session and edit operation. Topology Exceptions arise when a topology rule is purposefully violated. Marking purposeful topology errors as exceptions allows other clients of the topology to handle them in an appropriate or specific manner, e.g., in reporting or symbolization.
Note that it is also possible to demote an exception or mark the exception as an error with the ITopologyRuleContainer::DemoteFromRuleException method.

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