org.eclipse.core.commands.operations.IUndoableOperation

IUndoableOperation defines an operation that can be executed, undone, and redone. Operations typically have fully defined parameters. That is, they are usually created after the user has been queried for any input needed to define the operation.

Operations determine their ability to execute, undo, or redo according to the current state of the application. They do not make decisions about their validity based on where they occur in the operation history. That is left to the particular operation history.

      fPreservedRedoModificationStamp= event.getModificationStamp();


      // record the current valid state for the top operation in case it
      // remains the
      // top operation but changes state.
      IUndoableOperation op= fHistory.getUndoOperation(fUndoContext);
      boolean wasValid= false;
      if (op != null)
        wasValid= op.canUndo();
      // Process the change, providing the before and after timestamps
      processChange(event.getOffset(), event.getOffset()
          + event.getLength(), event.getText(), fReplacedText,
          fPreservedUndoModificationStamp,
