Accessors

disposed

  • get disposed(): boolean

  • Gets the disposed status of the entity.

    Returns boolean

    The disposed status.

elementsResolved

  • get elementsResolved(): any[]

  • An array of the elements that this component instance exposes. In the case that this component does not expose any elements of its own, this will be an array of the elements exposed by this component's children.

    Returns any[]

lockedResolved

  • get lockedResolved(): boolean

  • Returns true if this component, or any of its parents, are marked as locked.

    Returns boolean

Constructors

constructor

Methods

addBehavior

  • addBehavior(b): void

  • Adds a behavior to the component.

    Parameters

    • b: Behavior<Component<any, ConstructorProps>>

      The behavior to add.

    Returns void

appendChild

  • appendChild(c): void

  • Adds the supplied component instance as a child of this component, removing it from any existing parent.

    Parameters

    • c: Component<any, ConstructorProps>

      The component instance to add

    Returns void

constructChildren

  • constructChildren(children, contextManager?): void

  • Constructs the children of this component.

    Parameters

    • children: ComponentChildren
    • OptionalcontextManager: ContextManager

    Returns void

dispose

getBehavior

  • getBehavior<T>(type): undefined | InstanceType<T>

  • Gets a behavior of a specific type from the component.

    Type Parameters

    • T extends (new (contextManager: ContextManager, instance: Component<any, ConstructorProps>, ...args: any[]) => Behavior<Component<any, ConstructorProps>>)

      The behavior type.

    Parameters

    • type: T

      The type of behavior to get.

    Returns undefined | InstanceType<T>

    The behavior of the specified type, or undefined if no such behavior exists.

getBehaviors

  • getBehaviors<T>(type): InstanceType<T>[]

  • Gets all behaviors of a specific type from the component.

    Type Parameters

    • T extends (new (contextManager: ContextManager, instance: Component<any, ConstructorProps>, ...args: any[]) => Behavior<Component<any, ConstructorProps>>)

      The behavior type.

    Parameters

    • type: T

      The type of behaviors to get.

    Returns InstanceType<T>[]

    An array of behaviors of the specified type.

getZComponentInstance

  • getZComponentInstance<T>(type?): T

  • Get the instance of the ZComponent that constructed this entity.

    If you pass the class of a ZComponent as the type parameter, this function will ensure that it returns an instance of that ZComponent. If this component or behavior was constructed by a different ZComponent class, or by a different entity altogether, the function with throw an error.

    Type Parameters

    • T extends ZComponent<any, T> = ZComponent<any>

    Parameters

    • Optionaltype: ConstructorForComponent<T>

      The ZComponent class that you are expecting to receive

    Returns T

    The instance of the ZComponent that constructed this component or behavior

register

  • register<Args>(evt, fn, priority?): any

  • Register a function to be called when an Event is fired, or an Observable's value changes. The function will only be bound to the underlying Event or Observable while this entity is enabled.

    Using this function, rather than attaching your handler directly to the Event or Observable, ensures your handler is automatically released when this entity is disposed.

    Type Parameters

    • Args extends any[]

    Parameters

    • evt: Event<Args>

      The Event or Observable to listen to

    • fn: ((...args: Args) => void)

      A function that will be called when the event fires, or the Observable value changes

        • (...args): void

        • Parameters

          Returns void

    • Optionalpriority: number

    Returns any

  • register<Args>(evt, fn, options?): any

  • Type Parameters

    • Args extends any[]

    Parameters

    Returns any

  • register<Type>(observable, fn, priority?): any

  • Type Parameters

    • Type

    Parameters

    • observable: Observable<Type, never>
    • fn: ((v: Type) => void)
        • (v): void

        • Parameters

          Returns void

    • Optionalpriority: number

    Returns any

  • register<Type>(observable, fn, options?): any

  • Type Parameters

    • Type

    Parameters

    Returns any

remove

  • remove(): void

  • Removes this component from its parent component.

    Returns void

removeBehavior

  • removeBehavior(b): void

  • Removes a behavior from the component.

    Parameters

    • b: Behavior<Component<any, ConstructorProps>>

      The behavior to remove.

    Returns void

removeChild

  • removeChild(c): void

  • Removes the supplied component instance from the list of children.

    Parameters

    • c: Component<any, ConstructorProps>

      The component to remove

    Returns void

unregister

  • unregister<Args>(evt, fn): any

  • Unregisters a function that was previously registered to an Event or Observable.

    Type Parameters

    • Args extends any[]

    Parameters

    • evt: Event<Args>

      The Event or Observable

    • fn: ((...args: Args) => void)

      The function that was passed in the call to register

        • (...args): void

        • Parameters

          Returns void

    Returns any

  • unregister<Type>(observable, fn): any

  • Type Parameters

    • Type

    Parameters

    • observable: Observable<Type, never>
    • fn: ((v: Type) => void)
        • (v): void

        • Parameters

Other

Readonlytags

tags: Observable<string[], never>

An array of string 'tags' assocated with this component.

The getComponentsByTag(mgr, tag) function can be used to get an array of components with the supplied tag.

By default, tags are scoped to the ZComponent instance that a component is constructed by. Tags that begin with global: are scoped to the experience as a whole.

Properties - Behavior

Readonlyenabled

enabled: Observable<boolean, never>

If false, this entity and its children will no longer participate in the experience.

Note - to read this value, you may wish to use enabledResolved which will be false if this entity, or any of its parents, have enabled set to false.

The precise implications of enabled being false will vary between entities, but in general disabled entities:

  • should not emit any events,
  • should not take any action, e.g. navigate the user to a different page,
  • should not perform any network communication,
  • should not make changes to other behaviors or components in the experience,
  • should minimise any runtime performance cost (e.g. detach from any frame handlers).

ReadonlyenabledResolved

enabledResolved: Observable<boolean, never>

This will have value false if this entity, or any of its parents, have enabled set to false.

To change the enabled status of this entity, use the enabled property instead.

The precise implications of enabled being false will vary between entities, but in general disabled entities:

  • should not emit any events,
  • should not take any action, e.g. navigate the user to a different page,
  • should not perform any network communication,
  • should not make changes to other behaviors or components in the experience,
  • should minimise any runtime performance cost.

Disabled entities will typically remain visible (if they have a visible appearance).
