org.apache.tinkerpop.gremlin.process.traversal.strategy.decoration

## Class SubgraphStrategy

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.DecorationStrategy>
  - - org.apache.tinkerpop.gremlin.process.traversal.strategy.decoration.SubgraphStrategy

- All Implemented Interfaces:
    Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.DecorationStrategy>, TraversalStrategy.DecorationStrategy

      public final class SubgraphStrategy
      extends AbstractTraversalStrategy<TraversalStrategy.DecorationStrategy>
      implements TraversalStrategy.DecorationStrategy

  This `TraversalStrategy` provides a way to limit the view of a `Traversal`. By providing `Traversal` representations that represent a form of filtering criterion for vertices and/or edges, this strategy will inject that criterion into the appropriate places of a traversal thus restricting what it traverses and returns.

  - ### Method Detail

    - #### apply

          public void apply(Traversal.Admin<?,?> traversal)

      Specified by:
        `apply` in interface `TraversalStrategy<TraversalStrategy.DecorationStrategy>`

    - #### getConfiguration

          public Configuration getConfiguration()

      Description copied from interface: `TraversalStrategy`
      Get the configuration representation of this strategy. This is useful for converting a strategy into a serialized form.
      Specified by:
        `getConfiguration` in interface `TraversalStrategy<TraversalStrategy.DecorationStrategy>`
      Returns:
        the configuration used to create this strategy

    - #### applyPost

          public Set<Class<? extends TraversalStrategy.DecorationStrategy>> applyPost()

      Description copied from interface: `TraversalStrategy`
      The set of strategies that must be executed after this strategy is executed. If there are no ordering requirements, the default implementation returns an empty set.
      Specified by:
        `applyPost` in interface `TraversalStrategy<TraversalStrategy.DecorationStrategy>`
      Returns:
        the set of strategies that must be executed post this one

    - #### getVertexCriterion

    - #### getEdgeCriterion

          public Traversal<Edge,?> getEdgeCriterion()

    - #### getVertexPropertyCriterion

          public Traversal<VertexProperty,?> getVertexPropertyCriterion()
