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

## Class ByModulatorOptimizationStrategy

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy>
  - - org.apache.tinkerpop.gremlin.process.traversal.strategy.optimization.ByModulatorOptimizationStrategy

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

      public final class ByModulatorOptimizationStrategy
      extends AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy>
      implements TraversalStrategy.OptimizationStrategy

  This strategy looks for standard traversals in by-modulators and replaces them with more optimized traversals (e.g. `TokenTraversal`) if possible.

    - #### instance

          public static ByModulatorOptimizationStrategy instance()

    - #### apply

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

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

    - #### applyPrior

          public Set<Class<? extends TraversalStrategy.OptimizationStrategy>> applyPrior()

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