public class Scheduler<T>
extends java.lang.Object
implements java.lang.Iterable<T>

Positional object container. Objects can be added to a scheduler at a certain position (or priority) and can be retrieved later on in their position + added order. All the objects of a scheduler can be iterated in order or objects of a cetain position can be retrieved for iteration.
