All Implemented Interfaces:

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

public final class AsStringGlobalStep<S,E>
extends ScalarMapStep<S,E>

Reference implementation for asString() step, a mid-traversal step which returns the incoming traverser value as a string. A null traverser raises an IllegalArgumentException.
