public interface QueueReceiver extends MessageConsumer
QueueReceiver
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 the QueueReceiver
s.
If a QueueReceiver
specifies a message selector, the messages that are not selected remain on the queue. By
definition, a message selector allows a QueueReceiver
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. Only QueueReceiver
s without a message selector will read messages in message producer
order.
Creating a MessageConsumer
provides the same features as creating a QueueReceiver
. A
MessageConsumer
object is recommended for creating new code. The QueueReceiver
is provided to support
existing code.
