Interface Transition<R>

Type Parameters:
R - The type of the resource whose entrance will be transitioned.
All Known Implementing Classes:
DrawableCrossFadeTransition, NoTransition, ViewPropertyTransition, ViewTransition
public interface Transition<R>
An interface that allows a transition to be applied to Views in Targets in across resource types. Targets that wrap views will be able to provide all of the necessary arguments and start the transition. Those that do not will be unable to provide the necessary arguments and will therefore be forced to ignore the transition. This interface is a compromise that allows view specific transition in Glide's complex world of arbitrary resource types and arbitrary target types.
