ForwardingSimpleBasePlayer

A SimpleBasePlayer that forwards all calls to another Player instance.

A base implementation for Player that reduces the number of methods to implement to a minimum.

Implementation notes:

Subclasses must override getState to populate the current player state on request.
The State should set the available commands to indicate which Player methods are supported.
All setter-like player methods (for example, setPlayWhenReady) forward to overridable methods (for example, handleSetPlayWhenReady) that can be used to handle these requests. These methods return a ListenableFuture to indicate when the request has been handled and is fully reflected in the values returned from getState. This class will automatically request a state update once the request is done. If the state changes can be handled synchronously, these methods can return Guava's immediateVoidFuture.
Subclasses can manually trigger state updates with invalidateState, for example if something changes independent of Player method calls.

This base class handles various aspects of the player implementation to simplify the subclass:

The State can only be created with allowed combinations of state values, avoiding any invalid player states.
Only functionality that is declared as available needs to be implemented. Other methods are automatically ignored.
Listener handling and informing listeners of state changes is handled automatically.
The base class provides a framework for asynchronous handling of method calls. It changes the visible playback state immediately to the most likely outcome to ensure the user-visible state changes look like synchronous operations. The state is then updated again once the asynchronous method calls have been fully handled.
