com.esri.arcgis.networkanalyst
Class INAContextHelperProxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.networkanalyst.INAContextHelperProxy

All Implemented Interfaces:

INAContextHelper, Externalizable, Serializable

public class INAContextHelperProxy
extends com.esri.arcgis.interop.Dispatch
implements INAContextHelper, Serializable

Provides access to the helper class to get the network analysis context.

Remarks

The INAContextHelper interface is the main interface of the NAContextHelper object whose purpose is to maintain a weak reference to the NAContext to avoid circular references.

When passed a reference to a INAContextHelper interface, it is because you should not have a strong reference to the NAContext object itself. Instead, keep a reference to the NAContextHelper and get the NAContext object from the NAContext property on the INAContextHelper interface instead.

Product Availability

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

The network analysis context.

Remarks

NAContext returns the NAContext.

When passed a reference to an INAContextHelper interface, it is because you should not have a strong reference to the NAContext object itself. Instead, keep a reference to the NAContextHelper and get the NAContext object from the NAContext property on the INAContextHelper interface instead.
