com.esri.arcgis.geodatabase
Interface ITopologyClass

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

FeatureClass, ITopologyClassProxy

public interface ITopologyClass

extends java.io.Serializable

Provides access to topology class members.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Remarks

The ITopologyClass interface provides read-only access to the properties of feature classes in a Topology. Most of these properties are specified when the feature class is added to the Topology.

Method Summary

ITopology	getTopology() The Topology associated with the class.
double	getWeight() The weight of the class in the topology.
int	getXYRank() The XY rank of the class in the topology.
int	getZRank() The Z rank of the class in the topology.
boolean	isEventNotificationOnValidate() Indicates if event notification is fired on validate.
boolean	isInTopology() Indicates if the class is in a topology.

Method Detail

getTopology

public ITopology getTopology()
                      throws java.io.IOException,
                             AutomationException

The Topology associated with the class.

Supported Platforms

Windows, Solaris, Linux

Remarks

Returns the Topology this FeatureClass is associated with. A FeatureClass can be associated with only 1 Topology.

Returns:

A reference to a com.esri.arcgis.geodatabase.ITopology

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isInTopology

public boolean isInTopology()
                     throws java.io.IOException,
                            AutomationException

Indicates if the class is in a topology.

Returns:

The inTopology

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getWeight

public double getWeight()
                 throws java.io.IOException,
                        AutomationException

The weight of the class in the topology.

Supported Platforms

Windows, Solaris, Linux

Remarks

The Weight of the feature class is a long between 1 and 10. This property is not currently implemented.

Returns:

The weight

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getXYRank

public int getXYRank()
              throws java.io.IOException,
                     AutomationException

The XY rank of the class in the topology.

Supported Platforms

Windows, Solaris, Linux

Remarks

The XYRank of a feature class in the topology is a long between 1 and 50. It represents the relative accuracy of the features in the feature class with respect to their surrounding features.

Returns:

The xYRank

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getZRank

public int getZRank()
             throws java.io.IOException,
                    AutomationException

The Z rank of the class in the topology.

Supported Platforms

Windows, Solaris, Linux

Remarks

The ZRank of a feature class in the topology is a long between 1 and 50. It represents the relative accuracy of the features in the feature class with respect to their surrounding features. If a feature class is not Z aware it will return a ZRank of zero.

Returns:

The zRank

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isEventNotificationOnValidate

public boolean isEventNotificationOnValidate()
                                      throws java.io.IOException,
                                             AutomationException

Indicates if event notification is fired on validate.

Supported Platforms

Windows, Solaris, Linux

Remarks

EventNotificationOnValidate returns a Boolean value indicating if the ITopologyClassEvents::OnValidate event is broadcast when the Topology of the participating feature class is validated. The EventNotificationOnValidate property is only set when the feature class is added to the Topology and can only be set if the Topology is created programmatically. Feature classes participating in topologies created with the use of the Topology Wizard in ArcCatalog, return False for EventNotificationOnValidate.

Returns:

The eventNotification

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
