Description copied from interface: ParallelAppBase

Partial Evaluation to implement.

Specified by:

PEval in interface ParallelAppBase<Long,Long,Double,Long,BFSContext>

Parameters:

fragment - fragment. The graph fragment providing accesses to graph data.

context - context. User defined context which manages data during the whole computations.
