| The UndoManager class manages the history of editing operations on a text flow so |
| that these operations can be undone and redone. |
| |
| <p>The undo manager maintains two stacks of IOperation objects. When a reversible |
| operation is executed, it is placed on the undo stack. If that operation is undone, |
| it is removed from the undo stack, reversed, and placed on the redo stack. Likewise, |
| if that operation is then redone, it is removed from the redo stack, re-executed, and |
| then placed onto the undo stack again. If another operation is executed first, the redo |
| stack is cleared.</p> |
| |
| <p>If the TextFlow is modified directly (not via |
| calls to the edit manager, but directly via calls to the managed FlowElement objects), then the edit manager |
| clears the undo stack to prevent the stack from getting out of sync with the current state.</p> |
