C# Class Smrf.NodeXL.Adapters.GraphAdapterBase

Base class for graph adapters.

This abstract class can serve as a base class for implementations. Its implementations of the public methods provide error checking but defer the actual work to protected abstract methods.

Inheritance: AdapterBase, IGraphAdapter
