activate

• activate(_on): void

• De- / Activate this node. Inactive nodes will not be processed by the renderer.

  Parameters

  • _on: boolean

  Returns void

addChild

• addChild(_child): void

• Adds the given reference to a node to the list of children, if not already in

  Parameters

  • _child: Node

  Returns void

  Throws

  Error when trying to add an ancestor of this

• addChild(_child, _index): void

• Adds the given reference to a node to the list of children at the given index. If it is already a child, it is moved to the new position.

  Parameters

  • _child: Node
  • _index: number

  Returns void

addComponent

• addComponent(_component): void

• Attach the given component to this node

  Parameters

  • _component: Component

  Returns void

addEventListener

• addEventListener(_type, _handler, _capture?): void

• Adds an event listener to the node. The given handler will be called when a matching event is passed to the node. Deviating from the standard EventTarget, here the _handler must be a function and _capture is the only option.

  Parameters

  • _type: string
  • _handler: EventListenerUnified
  • _capture: boolean = false

  Returns void

applyAnimation

• applyAnimation(_mutator): void

• Applies a Mutator from Animation to all its components and transfers it to its children.

  Parameters

  • _mutator: Mutator

  Returns void

attach

• attach(_component): void

• Attach the given component to this node. Identical to addComponent

  Parameters

  • _component: Component

  Returns void

broadcastEvent

• broadcastEvent(_event): void

• Broadcasts a synthetic event to this node and from there to all nodes deeper in the hierarchy, invoking matching handlers of the nodes listening to the capture phase. Watch performance when there are many nodes involved

  Parameters

  • _event: Event

  Returns void

detach

• detach(_component): void

• Detach the given component from this node. Identical to removeComponent

  Parameters

  • _component: Component

  Returns void

dispatchEvent

• dispatchEvent(_event): boolean

• Dispatches a synthetic event to target. This implementation always returns true (standard: return true only if either event's cancelable attribute value is false or its preventDefault() method was not invoked) The event travels into the hierarchy to this node dispatching the event, invoking matching handlers of the nodes ancestors listening to the capture phase, than the matching handler of the target node in the target phase, and back out of the hierarchy in the bubbling phase, invoking appropriate handlers of the anvestors

  Parameters

  • _event: Event

  Returns boolean

dispatchEventToTargetOnly

• dispatchEventToTargetOnly(_event): boolean

• Dispatches a synthetic event to target without travelling through the graph hierarchy neither during capture nor bubbling phase

  Parameters

  • _event: Event

  Returns boolean

findChild

• findChild(_search): number

• Returns the position of the node in the list of children or -1 if not found

  Parameters

  • _search: Node

  Returns number

getAllComponents

• getAllComponents(): Component[]

• Returns a list of all components attached to this node, independent of type.

  Returns Component[]

getAncestor

• getAncestor(): Node

• Traces back the ancestors of this node and returns the first

• Returns child at the given index in the list of children

  Parameters

  Returns Node

getChildren

• getChildren(): Node[]

• Returns a clone of the list of children

  Returns Node[]

getChildrenByName

• getChildrenByName(_name): Node[]

• Returns an array of references to childnodes with the supplied name.
