Examples with ActiveMQBuffer org.apache.activemq.artemis.api.core.ActiveMQBuffer used on opensource projects

Example 1 with ActiveMQBuffer

use of org.apache.activemq.artemis.api.core.ActiveMQBuffer in project activemq-artemis by apache.

the class ClientSessionImpl method convert.

/**
 * If you ever tried to debug XIDs you will know what this is about.
 * This will serialize and deserialize the XID to the same way it's going to be printed on server logs
 * or print-data.
 * <p>
 * This will convert to the same XID deserialized on the Server, hence we will be able to debug eventual stuff
 *
 * @param xid
 * @return
