Interface MQReceiveExit
-
- All Known Implementing Classes:
- MQExternalReceiveExit, MQReceiveExitChain
public interface MQReceiveExit
The receive exit interface allows you to examine, and possibly alter, the data received from the queue manager by the IBM MQ Client for Java.Note: This interface does not apply when connecting directly to IBM MQ in bindings mode.
To provide your own receive exit, define a class that implements this interface. Create a new instance of your class and assign it to the MQEnvironment.receiveExit field before constructing your MQQueueManager object.
For example,
// in MyReceiveExit.java class MyReceiveExit implements MQReceiveExit { // you must provide an implementation of the receiveExit method public byte[] receiveExit(MQChannelExit channelExitParms, MQChannelDefinition channelDefinition, byte[] agentBuffer) { // your exit code goes here... } } // in your main program... MQEnvironment.receiveExit = new MyReceiveExit(); ... // other initialisation MQQueueManager qMgr = new MQQueueManager("");

receiveExit
byte[] receiveExit(MQChannelExit channelExitParms, MQChannelDefinition channelDefinition, byte[] agentBuffer)
The receive exit method that your class must provide. It is invoked whenever the IBM MQ Client for Java receives a message from the queue manager.- Parameters:
channelExitParms
- contains information about the context in which the exit is being invoked.channelExitParms.exitResponse
is a parameter which you use to tell the IBM MQ Client for Java what action to take next.channelDefinition
- contains details of the channel through which all communications with the queue manager take place.agentBuffer
- contains the data received from the queue manager ifchannelExitParms.exitReason
is MQChannelExit.MQXR_XMIT. Otherwise agentBuffer is null.- Returns:
- the data to be processed. If the exit response code (in channelExitParms) is MQXCC_OK,
the MQ Client for Java can now process the data. The simplest receive exit, therefore,
consists of the single line:
return agentBuffer;
