ForwardingSimpleBasePlayer


@UnstableApi
public class ForwardingSimpleBasePlayer extends SimpleBasePlayer


A SimpleBasePlayer that forwards all calls to another Player instance.

The class can be used to selectively override getState or handle{Action} methods:

new ForwardingSimpleBasePlayer(player) {
  
  protected State getState() {
    State state = super.getState();
    // Modify current state as required:
    return state.buildUpon().setAvailableCommands(filteredCommands).build();
  }

  
  protected ListenableFuture<?> handleSetRepeatMode(int repeatMode) {
    // Modify actions by directly calling the underlying player as needed:
    getPlayer().setShuffleModeEnabled(true);
    // ..or forward to the default handling with modified parameters:
    return super.handleSetRepeatMode(Player.REPEAT_MODE_ALL);
  }
}
This base class handles many aspect of the player implementation to simplify the subclass, for example listener handling. See the documentation of SimpleBasePlayer for a more detailed description.
