Method Summary

IGeometry	getGeometry() The geometry of the topology element.
IEnumTopologyParent	getParents() The set of parents (features) of this topology element.
boolean	isDeleted() Indicates if this element has been deleted from its containing topology graph.
boolean	isSelected() Indicates if this element is part of its containing topology graph's selected set.
boolean	isVisited() Indicates if the topology element has been visited.
void	queryGeometry(IGeometry geometry) Copies the element's geometry into the specified geometry.
void	setVisited(boolean isVisited) Indicates if the topology element has been visited.

Method Detail

getGeometry

IGeometry getGeometry()
                      throws IOException,
                             AutomationException

The geometry of the topology element.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

A reference to a com.esri.arcgis.geometry.IGeometry

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isSelected

boolean isSelected()
                   throws IOException,
                          AutomationException

Indicates if this element is part of its containing topology graph's selected set.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The selected

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryGeometry

void queryGeometry(IGeometry geometry)
                   throws IOException,
                          AutomationException

Copies the element's geometry into the specified geometry.

Remarks

The Geometry parameter must be an instance of an appropriate type of geometry for the topology element being called. For example, if the topology element is a node, a new point should be created and passed as the parameter, and if the topology element is an edge, a new polyline should be created and passed as the parameter.
