Class OperationQueue

java.lang.Object
  mauda.operation.OperationQueue

All Implemented Interfaces:

java.lang.Comparable

public class OperationQueue
extends java.lang.Object
implements java.lang.Comparable

Storage of a collection of multiple base-operations. Additionally this class has several needed methods to manipulate or generate new OperationQueue's. For Example:
- shuffle
- get all permutations of the operations the queue holds
- execution of the whole cue
- load
- save
