Recyclable<T> class Null safety

An interface that Controller subclasses implement to generate a controller for each request.

If a Controller implements this interface, a Controller is created for each request. Controllers must implement this interface if they declare setters or non-final properties, as those properties could change during request handling.

A controller that implements this interface can store information that is not tied to the request to be reused across each instance of the controller type by implementing recycledState and restore. Use these methods when a controller needs to construct runtime information that only needs to occur once per controller type.
