Package org.apache.giraph.block_app.framework.api Description

Interfaces representing full API to the underlying graph processing system. Framework implementation is fully contained within package org.apache.giraph.block_app.framework, given implementation of interfaces defined here. He have two such implementations: - one relying on Giraph, distributed graph processing system, connecting all methods to it's internals - one having a fully contained local implementation, executing applications on a single machine. Avoiding overheads of Giraph being distributed, it allows very efficient evaluation on small graphs, especially useful for fast unit tests. You could potentially use a different graph processing system, to execute any Block Application, by implementing these interfaces.
