Interface ForwardGroup<T>

All Known Implementing Classes:
JobVertexForwardGroup, StreamNodeForwardGroup
public interface ForwardGroup<T>
A forward group is a set of job vertices or stream nodes connected via forward edges. Parallelisms of all job vertices or stream nodes in the same ForwardGroup must be the same.
