Constructor Detail

TopologyNode

public TopologyNode(java.lang.Object obj)
             throws java.io.IOException

Construct a TopologyNode using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to TopologyNode.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
TopologyNode o = (TopologyNode)obj; // will not work

TopologyNode o = new TopologyNode(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:

java.io.IOException - if there are interop problems TopologyNode theTopologyNode = (TopologyNode) obj;
