javax.swing.undo.AbstractUndoableEdit.canUndo()
javax.swing.undo.CompoundEdit.canUndo()
javax.swing.undo.UndoManager.canUndo()
javax.swing.undo.UndoableEdit.canUndo()
Returns true if this edit may be undone. @return true if this edit may be undone
org.eclipse.core.commands.operations.IUndoableOperation.canUndo()

Returns whether the operation can be undone in its current state.

Note: The computation for this method must be fast, as it is called frequently. If necessary, this method can be optimistic in its computation (returning true) and later perform more time-consuming computations during the actual undo of the operation, returning the appropriate status if the operation cannot actually be undone at that time.
@return true if the operation can be undone;false otherwise.
org.eclipse.emf.common.command.CommandStack.canUndo()
Returns whether the top command on the stack can be undone. @return whether the top command on the stack can be undone.
org.eclipse.gef.commands.Command.canUndo()
org.enhydra.jawe.UndoHistoryManager.canUndo()
org.evolizer.daforjava.commands.CommandController.canUndo()
Check whether a command can be undone. @return True, if a command can be undone, otherwise false.
org.freeplane.core.undo.IUndoHandler.canUndo()
org.gdbms.engine.data.AlphanumericDataSource.canUndo()
org.gdbms.engine.data.SpatialDataSource.canUndo()
org.gdbms.engine.data.command.CommandStack.canUndo()
org.openbp.jaspira.undo.UndoMgr.canUndo()
Returns true if a undoable transition exists. @return boolean - true: undo transition exists.false: otherwise.
