Examples of ExecutionGroupVertexIterator

eu.stratosphere.nephele.executiongraph.ExecutionGroupVertexIterator
This class provides an implementation of the {@link Iterator} interface which allows totraverse an execution graph and visit every reachable group vertex exactly once. The order in which the group vertices are visited corresponds to the order of their discovery in a depth first search.
This class is not thread-safe.
