org.apache.tinkerpop.gremlin.process.traversal.util

## Class ScriptTraversal<S,E>

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.traversal.util.DefaultTraversal<S,E>
  - - org.apache.tinkerpop.gremlin.process.traversal.util.ScriptTraversal<S,E>

- All Implemented Interfaces:
    Serializable, AutoCloseable, Cloneable, Iterator<E>, Traversal<S,E>, Traversal.Admin<S,E>

      public final class ScriptTraversal<S,E>
      extends DefaultTraversal<S,E>

  ScriptTraversal encapsulates a `ScriptEngine` and a script which is compiled into a `Traversal` at `Admin#applyStrategies()`. This is useful for serializing traversals as the compilation can happen on the remote end where the traversal will ultimately be processed.

      Description copied from interface: `Traversal.Admin`
      Apply the registered `TraversalStrategies` to the traversal. Once the strategies are applied, the traversal is "locked" and can no longer have steps added to it. The order of operations for strategy applications should be: globally id steps, apply strategies to root traversal, then to nested traversals.
      Specified by:
        `applyStrategies` in interface `Traversal.Admin<S,E>`
      Overrides:
        `applyStrategies` in class `DefaultTraversal<S,E>`
      Throws:
        `IllegalStateException` - if the `TraversalStrategies` have already been applied
