Method Detail

getEdges

IEnumNodeEdge getEdges(boolean clockwise)
                       throws IOException,
                              AutomationException

The set of topological edges incident on this node.

Product Availability

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

Parameters:

clockwise - The clockwise (in)

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getDegree

int getDegree()
              throws IOException,
                     AutomationException

The number of edges entering and leaving this node. Closed edges are counted twice.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The degree

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isDegreeKnown

boolean isDegreeKnown()
                      throws IOException,
                             AutomationException

Indicates if the degree of this node is known. Nodes constructed from edges that are partially outside the build extent have unknown degrees.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The degreeKnown

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
