Protected functions

createEntranceTransition

protected fun createEntranceTransition(): Any

Create entrance transition. Subclass can override to load transition from resource or construct manually. Typically app does not need to override the default transition that browse and details provides.

runEntranceTransition

protected fun runEntranceTransition(entranceTransition: Any?): Unit

Run entrance transition. Subclass may use TransitionManager to perform go(Scene) or beginDelayedTransition(). App should not override the default implementation of browse and details fragment.
