Class MatchStep.TraversalWrapper<A,B>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.step.map.match.MatchStep.TraversalWrapper<A,B>

All Implemented Interfaces:

Comparable<MatchStep.TraversalWrapper<A,B>>

Enclosing class:

MatchStep<S,E>

public static class MatchStep.TraversalWrapper<A,B>
extends Object
implements Comparable<MatchStep.TraversalWrapper<A,B>>

A wrapper for a traversal in a query which maintains statistics about the traversal as it consumes inputs and produces outputs. The "branch factor" of the traversal is an important factor in determining its place in the query plan.
