Message property management

The following QAMessage methods can be used to manage message properties.

Note

You can get and set custom properties, but should only get predefined properties.

Example

// C++ example.
QAManagerFactory factory;
QAManager * mgr = factory->createQAManager();
mgr->open(AcknowledgementMode::EXPLICIT_ACKNOWLEDGEMENT);
QAMessage * msg = mgr->createTextMessage();
msg->setStringProperty( "tm_Subject", "Some message subject." );
mgr->putMessage( "myqueue", msg );

// C# example.
QAManager mgr = QAManagerFactory.Instance.CreateQAManager();
mgr.Open(AcknowledgementMode.EXPLICIT_ACKNOWLEDGEMENT);
QAMessage msg = mgr.CreateTextMessage();
msg.SetStringProperty( "tm_Subject", "Some message subject." );
mgr.PutMessage( "myqueue", msg );

// Java example
QAManager mgr = QAManagerFactory.getInstance().createQAManager();
mgr.open(AcknowledgementMode.EXPLICIT_ACKNOWLEDGEMENT);
QAMessage msg = mgr.createTextMessage();
msg.setStringProperty("tm_Subject", "Some message subject.");
mgr.putMessage("myqueue", msg);

-- SQL example
begin
    DECLARE @msgid VARCHAR(128);
    SET @msgid = ml_qa_createmessage();
    CALL ml_qa_setfloatproperty( @msgid, 'myfloatproperty1', -1.3e-5 );
    CALL ml_qa_setfloatproperty( @msgid, 'myfloatproperty2', 1.3e5 );
    CALL ml_qa_putmessage( @msgid, 'clientid\queuename' );
    COMMIT;
end
