Detailed Description

template<typename Adapter>
class Zoltan2::GraphModel< Adapter >

GraphModel defines the interface required for graph models.

The constructor of the GraphModel can be a global call, requiring all processes in the application to call it. The rest of the methods should be local methods.

The template parameter is an InputAdapter, which is an object that provides a uniform interface for models to the user's input data.

GraphModels may represent a local (on-process) graph or a global (all-communicator) graph.
