ForwardingPlayer


@UnstableApi
public class ForwardingPlayer implements Player


A Player that forwards method calls to another Player. Applications can use this class to suppress or modify specific operations, by overriding the respective methods.

Subclasses must ensure they maintain consistency with the Player interface, including interactions with Player.Listener, which can be quite fiddly. For example, if removing an available Player.Command and disabling the corresponding method, subclasses need to:

Many customization use-cases are instead better served by ForwardingSimpleBasePlayer, which allows subclasses to more concisely modify the behavior of an operation, or disallow a Player.Command. In many cases ForwardingSimpleBasePlayer should be used in preference to ForwardingPlayer.
