Interface NtxPageLifecycleEvent

public interface NtxPageLifecycleEvent
Event delivered to a node renderer's NTxNodeRenderer.onPageShow(NtxPageLifecycleEvent) / NTxNodeRenderer.onPageHide(NtxPageLifecycleEvent) hooks when the page that contains node() starts or stops being shown.

Hooks are the counterpart of NtxPageLifecycle.requestFrame(): use them for exactly-once side effects around a slide transition (start/stop an async computation, reset a chronometer, release a resource), not for per-frame work.
