AppActivityList

class AppActivityList

extends Component

Component that encapsulates a list of child activities; emits change events when the list changes (propagated from ManagedList) and when one of the activities becomes active or inactive.

Note: This class is used internally to represent ‘preset’ activities of an Application constructor. An instance of this class is available as Application.activities.

Constructor

(): AppActivityList

.count

number

The number of activities currently in the list.

.add()

(...activities: AppActivity[]): this

Add one or more child activities to the list.

.remove()

(activity: AppActivity): this

Remove given activity from the list. Does not throw an error if the activity was not included in the list.

.clear()

(): this

Clear the list by removing all activities in one go.

.get()

(index: number): AppActivity

Returns the activity at given position in the list.

.includes()

(activity: AppActivity): boolean

Returns true if the list includes given activity.

.forEach()

(callback: (target: AppActivity) => void): void

callback — the function to be called, with a single activity as the only argument.

Iterates over the activities in this list and invokes given callback for each activity.

.map()

<TResult>(callback: (target: AppActivity) => TResult): TResult[]

callback — the function to be called, with a single activity as the only argument.

Iterates over the activities in this list and invokes given callback for each activity, then returns an array with all callback return values.

Note: The behavior of this method is undefined if the activity list is changed while running.

.toArray()

(): AppActivity[]

Returns an array with all activities currently in this list.

.delegateEvent()

(e: ManagedEvent): void

Re-emits given event on this component; called for each event that is emitted by the encapsulated list (which also propagates events of type ActionEvent from all contained activities).
