Author:

Tim Fox, Jeff Mesnil HornetQ filters have the same syntax as JMS 1.1 selectors, but the identifiers are different. Valid identifiers that can be used are: HQPriority - the priority of the message HQTimestamp - the timestamp of the message HQDurable - "DURABLE" or "NON_DURABLE" HQExpiration - the expiration of the message HQSize - the encoded size of the full message in bytes HQUserID - the user specified ID string (if any) Any other identifiers that appear in a filter expression represent header values for the message String values must be set as SimpleString, not java.lang.String (see JBMESSAGING-1307). Derived from JBoss MQ version by, Norbert Lataille, Juha Lindfors, Jason Dillon, Scott Stark, Tim Fox
