I've seen a small number of posts that included code that used AQDequeueOption while dequeueing from an Oracle Advanced Queue, and I've seen some scanty JavaDoc about it. I haven't seen any general information about it, and it isn't mentioned at all in the Oracle® Database
Advanced Queuing User's Guide, 12c Release 2 (12.2).
Can anybody point me to some explanatory information about it? For example, is it only provided as an argument to dequeue, or can it also be used in other ways, for example, with a QueueReceiver somehow?
Conceptually Dequeue Options specify how you want to walk-through the queue, as described https://docs.oracle.com/cd/B19306_01/server.102/b14257/aq_opers.htm#i1006951 - Dequeue Options. AQDequeueOption materializes this concept on JDBC Api and can only be applied on dequeue method.
QueueReceiver is from another API, the javax.jms. In order to achieve the same result as using a Dequeue Option, you need to select the proper interface that has the desired behavior, e.g, QueueBrowser or QueueReceiver. (https://docs.oracle.com/javaee/7/api/javax/jms/QueueBrowser.html)
