我们可以为Java接口实施超时吗？

Question

I'm working on a game server based in java. My design on the server side is as follows.
The RuleEnforcer is passed in a list of IPlayers, and it initiates communication with the players. IPlayers is an interface, and i imagine implementing a dummy Player for testing purpose, a "smart" player, and also a player that eventually interacts with a remote client UI interface. In RuleEnforcer when player methods are called, it needs to ensure that the method returns (on time). eg:

for(player : players) {
    player.giveAcard(card);
}

giveACard has no return type, and the each player needs to just save the card and return immediately. But if a player implementation sleeps on the method call, the game is stuck. How do I account for that in my code ? One approach I can think of is to call player interactions in a different thread, and use wait. Is there any design that is applicable to this scenario, or is my approach wrong ?

Answer 1

yes you can create by this way. create a constructor

SimpleTimeLimiter()

Constructs a TimeLimiter instance using a Executors.newCachedThreadPool() to execute proxied method calls. method detail with new proxy....

public <T> T newProxy(T target,
             Class<T> interfaceType,
             long timeoutDuration,
             TimeUnit timeoutUnit)

then call with timeout...

callWithTimeout
public <T> T callWithTimeout(Callable<T> callable,
                    long timeoutDuration,
                    TimeUnit timeoutUnit,
                    boolean amInterruptible)

for reference use...new proxy..

public <T> T newProxy(T target,
             Class<T> interfaceType,
             long timeoutDuration,
             TimeUnit timeoutUnit)
