public final class SplitLocalStep<S,E>
extends StringLocalStep<S,E>
implements TraversalParent

Reference implementation for substring step, a mid-traversal step which returns a list of strings created by splitting the incoming string traverser around the matches of the given separator. A null separator will split the string by whitespaces. Null values from incoming traversers are not processed and remain as null when returned. If the incoming traverser is a non-String value then an IllegalArgumentException will be thrown.
