Interface INAContextHelper

All Superinterfaces:
Serializable
All Known Implementing Classes:
INAContextHelperProxy

public interface INAContextHelper
extends Serializable

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

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.
