Method Detail

add

protected void add(ServerRequest request)

Adds a request to this queue. The properties jacorb.poa.queue_{min,max,wait} specify what happens when the queue is full, i.e. when it already contains queue_max requests. If queue_wait is off, then this method does not add the request and throws a ResourceLimitReachedException. If queue_wait is on, then this method blocks until no more than queue_min requests are in the queue; it then adds the request, and returns.
