org.eclipse.ui.operations.LinearUndoViolationUserApprover

An operation approver that prompts the user to see if linear undo violations are permitted. A linear undo violation is detected when an operation being undone or redone shares an undo context with another operation appearing more recently in the history.

This class may be instantiated by clients.
@since 3.1


      // The second approver will prompt from this editor when an undo is attempted on an operation
      // and it is not the most recent operation in the editor.
      if (fLinearUndoViolationApprover != null)
        history.removeOperationApprover(fLinearUndoViolationApprover);
      fLinearUndoViolationApprover= new LinearUndoViolationUserApprover(undoContext, this);
      history.addOperationApprover(fLinearUndoViolationApprover);


    } else {
      // Use text operation actions (pre 3.1 style)
