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

## Class IdentityRemovalStrategy

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

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

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

  `IdentityRemovalStrategy` looks for `IdentityStep` instances and removes them. If the identity step is labeled, its labels are added to the previous step. If the identity step is labeled and it's the first step in the traversal, it stays.
