Here you receive the callback messages from xmlBlaster.

Specified by:

update in interface I_CallbackRaw

Parameters:

cbSessionId - The session ID specified by the client which registered the callback

updateKey - The arrived key in a flattened JXPath representation.

   /key/@oid                 -> Rugby
   /key/@contentMime         -> text/plain
   /key/@contentMimeExtended -> Version-1.0
   /key/child::node()        -> <myTeam>Munich<numPlayers>6</numPlayers></myTeam>
   ...
 

content - The binary message pay load

updateQos - The arrived key in a flattened JXPath representation.

   /qos/rcvTimestamp/@nanos                  -> 1042815836675000001
   /qos/methodName/text()                    -> update
   /qos/clientProperty[@name='myAge']/text() -> 12
   /qos/state/@id                            -> OK
