Question

I have a class A with a LinkedBlockingQueue as property. In one method of A, I call the LinkedBlockingQueue.put() method since I want to insert an item in the queue. But, if the queue is full, my thread will wait until space is available or until my thread is interrupted.

The problem is that even if my thread is interrupted, I want the item to be in the queue.

Is there a way to be sure that my item has been inserted in the queue?

Thanks

The only way I see is to call queue.put() in a loop. This way maybe

boolean added = false;

while ( !added){
    try{
        queue.put(value);
        added = true;
    }catch(InterruptedException ie){
        // do something if required

        // make sure to set the interrupted flag on the thread, since it was cleared
        // when the exception was thrown
        Thread.currentThread().interrupt();
    }
}

if(Thread.currentThread.isInterrupted()){
    // you were previously interrupted before, so try to exit gracefully
    return;
}
