Is there a bounded non-blocking Collection in Java?

Question

The only one I can find is the BoundedFIFOBuffer, which is deprecated. Any others?

Answer 1

I've been using Google Collections recently. I think you could have a Java Generics solution pretty easily with it. There is a class called ForwardingList which I think you could implement this idea pretty easily. Obviously not as easy as just using BoundedFifoBuffer (non-generic) or ArrayBlockingQueue.

final ArrayList realList = Lists.newArrayList();
final List list = new ForwardingList() {
    protected List delegate() {
        return realList;
    }

    public boolean add(MyObject obj) {
        if(delegate().size() > 100) return false;
        return delegate().add(obj);
    }
};
