com.esri.arcgis.geodatabase
Class IGraphProxy

java.lang.Object
  extended by com.esri.arcgis.interop.Dispatch
      extended by com.esri.arcgis.geodatabase.IGraphProxy
All Implemented Interfaces:
IGraph, Externalizable, Serializable
Direct Known Subclasses:
IGeometricNetworkProxy

public class IGraphProxy
extends com.esri.arcgis.interop.Dispatch
implements IGraph, Serializable

Provides access to members that manage graphs.

Remarks

The IGraph interface contains methods and properties which are used in conjunction with geometric networks. Many of the methods, such as Add, Init, Split and Merge are called internally from within other methods. For these methods, there may be an analogous method or series of methods available, consult the specific help file for that method.

The NetworkLoader object should be used for creating or building of geometric networks, in place of the Graph or GeometricNetwork objects.

Since IGeometricNetwork inherits from IGraph, all the methods on IGraph are available to IGeometricNetwork
