Class StemKeys

java.lang.Object

org.qdl_lang.variables.StemKeys

All Implemented Interfaces:

Iterable, Collection, Set

public class StemKeys
extends Object
implements Set

A set for looping through keys of a stem. This manages long indices and string keys. This will keep the keys in order and will process long keys first, then string keys.
N.B. it produces keys that are Objects.
