Detailed Description

A superclass that defines the interface to be implemented by all concrete grid connectivity classes.

Grid connectivity classes provide the mechanism to achieve the following:

Handling of partitioned/distributed data

Construct the neighboring topology information for each partition,e.g., used for creating communication lists and in computing statistics,i.e., average, mean, etc.

Creation of ghost layers

Provides the mechanism for automatically generating ghost information given a partitioned/distributed grid configuration.
