Properties

Static properties

  • Chevron-right icon

    className : string
    readonlystatic

    Name of the operation class used for serialization.

Methods

  • Chevron-right icon

    constructor( rootName, elementName, isAdd, document, baseVersion )

    Creates an operation that creates or removes a root element.

    Parameters

    rootName : string

    Root name to create or detach.

    elementName : string

    Root element name.

    isAdd : boolean

    Specifies whether the operation adds (true) or detaches the root (false).

    document : ModelDocument

    Document which owns the root.

    baseVersion : number

    Document version on which operation can be applied.

  • Chevron-right icon

    Creates and returns an operation that has the same parameters as this operation.

    Returns

    RootOperation

    Clone of this operation.

  • Chevron-right icon

    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    Keep in mind that tree model state may change since executing the original operation, so reverse operation will be "outdated".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

    RootOperation

    Reversed operation.

  • Chevron-right icon

    toJSON() → unknown

    Custom toJSON method to solve child-parent circular dependencies.

    Returns

    unknown

    Clone of this object with the operation property replaced with string.

  • Chevron-right icon

    _execute() → void
    internal

    Executes the operation - modifications described by the operation properties will be applied to the model tree.

    Returns

    void
  • Chevron-right icon

    _validate() → void
    internalinherited
