Constructor Detail

HornetQQueueBrowser

protected HornetQQueueBrowser(HornetQQueue queue,
                   String messageSelector,
                   ClientSession session)
                       throws JMSException

Throws:

JMSException

Method Detail

close

public void close()
           throws JMSException

Description copied from interface: QueueBrowser

Closes the QueueBrowser.

Since a provider may allocate some resources on behalf of a QueueBrowser outside the Java virtual machine, clients should close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

Specified by:

close in interface QueueBrowser

Throws:

JMSException - if the JMS provider fails to close this browser due to some internal error.

getEnumeration

public Enumeration getEnumeration()
                           throws JMSException

Description copied from interface: QueueBrowser

Gets an enumeration for browsing the current queue messages in the order they would be received.

Specified by:

getEnumeration in interface QueueBrowser

Returns:

an enumeration for browsing the messages

Throws:

JMSException - if the JMS provider fails to get the enumeration for this browser due to some internal error.

getMessageSelector

public String getMessageSelector()
                          throws JMSException

Description copied from interface: QueueBrowser

Gets this queue browser's message selector expression.

Specified by:

getMessageSelector in interface QueueBrowser

Returns:

this queue browser's message selector, or null if no message selector exists for the message consumer (that is, if the message selector was not set or was set to null or the empty string)

Throws:

JMSException - if the JMS provider fails to get the message selector for this browser due to some internal error.

getQueue

public Queue getQueue()
               throws JMSException

Description copied from interface: QueueBrowser

Gets the queue associated with this queue browser.

Specified by:

getQueue in interface QueueBrowser

Returns:

the queue

Throws:

JMSException - if the JMS provider fails to get the queue associated with this browser due to some internal error.

Overrides:
