  • delta : Delta

    inherited

    Delta which the operation is a part of. This property is set by the delta when the operations is added to it by the addOperation method.

    Returns

    Operation

    Clone of this operation.

  • getReversed() → Operation

    inherited

    Creates and returns a reverse operation. Reverse operation when executed right after the original operation will bring back tree model state to the point before the original operation execution. In other words, it reverses changes done by the original operation.

    Keep in mind that tree model state may change since executing the original operation, so reverse operation will be "outdated". In that case you will need to transform it by all operations that were executed after the original operation.

    Returns

    Operation

    Reversed operation.
