I

IEdgePortHandleProvider

Show Usages
An interface for classes that can yield IHandle implementations for the source and target ends of an IEdge.
Inheritance Hierarchy

Remarks

This interface will be queried by the default implementation of the IHandleProvider that is in the lookup of an IEdge. It is recommended to use this interface instead of the more generic IHandleProvider interface, because other generic code can then use this interface to gain access to a specific IHandle more easily.
