Properties

Static properties

  • className : String

    readonly inherited static

    Delta class name. Used by toJSON method for serialization and fromJSON during deserialization.

Methods

  • constructor()

    inherited

    Creates a delta instance.

  • addOperation( operation )

    inherited

    Add operation to the delta.

    Parameters

  • clone() → Delta

    inherited

    Creates and returns a delta that has the same parameters as this delta.

    Returns

    Delta

    Clone of this delta.

  • getReversed() → Delta

    inherited

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

    Keep in mind that tree model state may change since executing the original delta, so reverse delta may be "outdated".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

    Returns

    Delta

    Reversed delta.

  • toJSON() → Object

    inherited

    Custom toJSON method to make deltas serializable.

    Returns

    Object

    Clone of this delta with added class name.
