public interface QueueReceiver extends MessageConsumer
A client uses aQueueReceiver
object to receive messages that have been delivered to a queue.Although it is possible to have multiple
QueueReceiver
s for the same queue, the Jakarta Messaging API does not define how messages are distributed between theQueueReceiver
s.If a
QueueReceiver
specifies a message selector, the messages that are not selected remain on the queue. By definition, a message selector allows aQueueReceiver
to skip messages. This means that when the skipped messages are eventually read, the total ordering of the reads does not retain the partial order defined by each message producer. OnlyQueueReceiver
s without a message selector will read messages in message producer order.Creating a
MessageConsumer
provides the same features as creating aQueueReceiver
. AMessageConsumer
object is recommended for creating new code. TheQueueReceiver
is provided to support existing code.- Since:
- JMS 1.0
- Version:
- Jakarta Messaging 2.0
