Detailed Description

Zoltan::LoadBalance: A class for interfacing the Load Balancing functions of the Zoltan library in a C++/Object Oriented environment.

The Zoltan::LoadBalance class is a wrapper for the C functions at the top level interface of Zoltan. The primary differences include the removal the Zoltan_Struct parameter since this object is now stored in the class and the use of user derived classes from Zoltan::QueryObject and Zoltan::MigrationObject for support of the "callback" functionality used by Zoltan.
