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.

Returns whether the top command on the stack can be undone. @return whether the top command on the stack can be undone.

Check whether a command can be undone. @return True, if a command can be undone, otherwise false.
