/**
* A {@code QueueSession} object provides methods for creating {@code QueueReceiver}, {@code QueueSender},
* {@code QueueBrowser}, and {@code TemporaryQueue} objects.
*
*
* If there are messages that have been received but not acknowledged when a {@code QueueSession} terminates, these
* messages will be retained and redelivered when a consumer next accesses the queue.
*
*
* A {@code QueueSession} is used for creating Point-to-Point specific objects. In general, use the {@code Session}
* object. The {@code QueueSession} is used to support existing code. Using the {@code Session} object simplifies the
* programming model, and allows transactions to be used across the two messaging domains.
*
*
* A {@code QueueSession} cannot be used to create objects specific to the publish/subscribe domain. The following
* methods inherit from {@code Session}, but must throw an {@code IllegalStateException} if they are used from
* {@code QueueSession}:
*
*
* - {@code createDurableSubscriber}
*
- {@code createDurableConsumer}
*
- {@code createSharedConsumer}
*
- {@code createSharedDurableConsumer}
*
- {@code createTemporaryTopic}
*
- {@code createTopic}
*
- {@code unsubscribe}
*
