示例1: scopeCallbacks

public <T> ListenableFuture<T> scopeCallbacks(final ListenableFuture<T> callback) {
final ScopedObjects scope = getScope();

@Override
protected ListenableFuture<T> delegate() {
return callback;
}
@Override
public void addListener(Runnable listener, Executor exec) {
super.addListener(listener, scope(exec, scope));
}
};
}
示例2: wrapListenableFuture
import com.google.common.util.concurrent.ForwardingListenableFuture; //导入依赖的package包/类
private <T> ListenableFuture<T> wrapListenableFuture(final ListenableFuture<T> delegate) {
/*
* This creates a forwarding Future that overrides calls to get(...) to check, via the
* ThreadLocal, if the caller is doing a blocking call on a thread from this executor. If
* so, we detect this as a deadlock and throw an ExecutionException even though it may not
* be a deadlock if there are more than 1 thread in the pool. Either way, there's bad
* practice somewhere, either on the client side for doing a blocking call or in the
* framework's threading model.
