Examples of org.activemq.message.ActiveMQXid

org.activemq.message.ActiveMQXid

A ActiveMQXid object holds the distributed transaction id that is passed around in an ActiveMQ system.
Eventhough a Transaction Manager (TM) has his own Xid implementation that he uses when he talks to the our ActiveMQXAResource, we need to send the Xid data down to the server in our format.
ActiveMQ uses Strings as the transaction id. This class coverts an Xid to and from a string.
