public static void undo(UndoManager undoManager,
 UndoableOperation operation)
                 throws CannotUndoException

Performs undo of all operation from the top of the stack to the given one.

Parameters:

undoManager - the undo manager

operation - the operation

Throws:

CannotUndoException - when one of the operations throws it

redo

public static void redo(UndoManager undoManager,
 UndoableOperation operation)
                 throws CannotRedoException

Performs re-do of all operation from the top of the stack to the given one.

Parameters:

undoManager - the undo manager

operation - the operation

Throws:

CannotRedoException - when one of the operations throws it

addUndoOperationAndEvent

public static void addUndoOperationAndEvent(UndoManager undoManager,
 UndoableOperation operation,
 Object eventSource)

Adds the given operation to the undo stack and sends global undo event.

Parameters:

undoManager - the undo manager

operation - the operation to be added

eventSource - the object to be used as source of the undo event

startUndoGrouping

public static void startUndoGrouping()

Starts grouping of undo-able operations. All operations will be added to a group instead of adding to the undo manager stack. To stop grouping, call stopUndoGrouping(UndoManager um, Object eventSource). Calling it the group sill be added to the undo manager stack as one bulk operation. Note: the grouping is per thread.

• stopUndoGrouping(UndoManager um, Object eventSource)

stopUndoGrouping

public static void stopUndoGrouping(UndoManager undoManager,
 Object eventSource)

Stops the grouping of undo-able operations. The group sill be added to the undo manager stack as one bulk operation. See startUndoGrouping() for more details about operation grouping and how to start it. Note: the grouping is per thread.

Parameters:

undoManager - the undo manager

eventSource - the object to be used as source of undo event

• startUndoGrouping()

stopUndoGrouping

public static void stopUndoGrouping(UndoManager undoManager,
 Object eventSource,
 BulkUndoableOperation bulk)

getGroupedOperations

public static List<UndoableOperation> getGroupedOperations()

Returns list of currently grouped operations (See startUndoGrouping()).

Returns:

list of currently grouped operations

discardUndoGrouping

public static void discardUndoGrouping()

Discards undo grouping without adding any undo operations to undo manager.

• startUndoGrouping()
• stopUndoGrouping(UndoManager um, Object eventSource)

addOperationAndEventInternal

 UndoableOperation operation,
 Object eventSource)
