    The main data block (if any) attached to the element, taken from its model (if any).

    dataId: string

    The ID of the main data block (if any) of the element, taken from its model (if any).

    dataIndex: number

    The numerical index of the main data block (if any) of the element, taken from its model (if any).

    • Protected Function

      Parameters

      • properties: object

        Properties to set on the new instance, defaults already merged in.

      Returns object

      The created instance.

      customCreate

      The construction step behind create. Override it to change how instances of a class are built — to route through a factory, or to wrap the instance — while keeping the default-merging that create performs.

    • Function

      destroy

      Returns this

      Itself, allowing for method chaining.

      Destroys the node by removing it from the document and removing all its bound listeners.

    • Function

      initialize

      Returns void

      Initializes the element. It sets up the UI by calling the methods setupUIElements, setupUILayout, setupUIListeners, and setupChangedCallbacks (in this order, if they are defined). This function is called automatically in .setProperties() and when instantiating an element via element(). It is called only once per element (as it checks with the reflected initialized flag).

    • Function

      feedforward

      Parameters

      • Optionalproperties: FeedforwardProperties

        Properties to feed forward. Defaults to defaultFeedforwardProperties.

      Returns this

      Itself, allowing for method chaining.

      Push this element's feedforward properties down to its children, so newly added descendants pick up the same defaults.

    • Function

      clone

      Parameters

      Returns this

      The cloned element.

      Create a copy of this element. By default the copy carries the same properties and children but none of the bound listeners.
