public final class OperationHistoryFactory extends Object
This class is used to maintain the instance of the operation history that should be used by classes that access the undo or redo history and add undoable operations to the history.
It is intended that an application can create an operation history appropriate for its needs and set it into this class. Otherwise, a default operation history will be created. The operation history may only be set one time. All classes that access an operations history use this class to obtain the correct instance.
