Class FailStep<S>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.step.util.AbstractStep<S,S>

org.apache.tinkerpop.gremlin.process.traversal.step.sideEffect.SideEffectStep<S>

org.apache.tinkerpop.gremlin.process.traversal.step.sideEffect.FailStep<S>

All Implemented Interfaces:

Serializable, Cloneable, Iterator<Traverser.Admin<S>>, Step<S,S>

public class FailStep<S>
extends SideEffectStep<S>

Triggers an immediate failure of the traversal by throwing a RuntimeException. The exception thrown must implement the Failure interface.
