Provides access to the set of edges incident on the specified node.

Product Availability

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

Method Summary

int	getCount() The number of edges entering and leaving this node.
boolean	isClockwise() Indicates if this enumerator is returning edges in clockwise order, or false if it is returning them in counterclockwise order.
void	next(ITopologyEdge[] nextEdge, boolean[] atFrom) Returns the next edge in clockwise or counterclockwise order about the node.
void	reset() Resets this eumerator.

Method Detail

reset

void reset()
           throws IOException,
                  AutomationException

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

Supported Platforms

Windows, Solaris, Linux

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

next

void next(ITopologyEdge[] nextEdge,
          boolean[] atFrom)
          throws IOException,
                 AutomationException

Returns the next edge in clockwise or counterclockwise order about the node. 'atFrom' is true if the from point of the edge is incident on this node.
