Class SubgraphStrategy

java.lang.Object

com.tinkerpop.gremlin.structure.strategy.SubgraphStrategy

All Implemented Interfaces:

GraphStrategy

public final class SubgraphStrategy
extends java.lang.Object
implements GraphStrategy

A GraphStrategy which creates a logical subgraph to selectively include vertices and edges of a Graph according to provided criteria. A vertex is in the subgraph if it meets the specified vertexPredicate. An edge is in the subgraph if it meets the specified edgePredicate and its associated vertices meet the specified vertexPredicate.
