Class Summary

Class	Description
AbstractPiece<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable,WV,WM extends org.apache.hadoop.io.Writable,S>	Parent of all Pieces, contains comprehensive list of methods Piece can support.
DefaultParentPiece<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable,WV,WM extends org.apache.hadoop.io.Writable,S>	Additional abstract implementations for all pieces to be used.
Piece<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable,S>	Piece that should be extended in common usecases, when we want to be: - sending and then receiving messages from vertices - sending data to be aggregated from workers to master - sending values from master, via aggregators, to workers (basically - we don't want to use WorkerContext)
PieceWithWorkerContext<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable,WV,WM extends org.apache.hadoop.io.Writable,S>	Piece that should be extended when WorkerContext is used.

Single execution object - Piece, and related classes. AbstractPiece is parent class of all Pieces. Most frequentlly users should extend Piece class itself
