Description

Store contextual information about the children (= nested) RouterOutlet

Members

onChildOutletCreated(childName: string, outlet: RouterOutlet): void

Called when a RouterOutlet directive is instantiated

onChildOutletDestroyed(childName: string): void

Called when a RouterOutlet directive is destroyed. We need to keep the context as the outlet could be destroyed inside a NgIf and might be re-created later.

onOutletDeactivated(): Map<string, OutletContext>

Called when the corresponding route is deactivated during navigation. Because the component get destroyed, all children outlet are destroyed.

onOutletReAttached(contexts: Map<string, OutletContext>)

getOrCreateContext(childName: string): OutletContext

getContext(childName: string): OutletContext | null
