use of com.datatorrent.netlet.util.CircularBuffer in project apex-core by apache.

the class BufferServerSubscriber method onMessage.

@Override

    Slice f;
    if (freeFragments.isEmpty()) {

        f.buffer = buffer;
        f.offset = offset;
        f.length = length;
    }
    if (!offeredFragments.offer(f)) {

                suspendRead();
                suspended = true;
            }
            int newsize = offeredFragments.capacity() == MAX_SENDBUFFER_SIZE ? offeredFragments.capacity() : offeredFragments.capacity() << 1;
            backlog.add(offeredFragments = new CircularBuffer<>(newsize));
            offeredFragments.add(f);
        }
    }
