Class TraversalMatrix<S,E>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.util.TraversalMatrix<S,E>

public final class TraversalMatrix<S,E>
extends Object

A TraversalMatrix provides random, non-linear access to the steps of a traversal by their step id. This is useful in situations where traversers becomes detached from their traversal (and step) and later need to be re-attached. A classic use case is TraversalVertexProgram on GraphComputer.
