Habarisoft released the 2018.10 version of its Object Pascal STOMP client libraries for application integration with open source message brokers (Apache ActiveMQ, Artemis, OpenMQ and RabbitMQ).

New in this release

  • new simple API, based on interfaces MQContext, MQProducer and MQConsumer (the old API still may be used)

Example:

procedure TNewApiTests.TestSendMessage;
var
  Factory: IConnectionFactory;
  Context: IMQContext;
  Destination: IQueue;
  Producer: IMQProducer;
  Consumer: IMQConsumer;
  TextMessage: ITextMessage;
begin
  Factory := TBTConnectionFactory.Create;

  Context := Factory.CreateContext;
  try
    Destination := Context.CreateQueue('example_queue');

    Producer := Context.CreateProducer;
    Producer.Send(Destination, 'Hello World');

    Consumer := Context.CreateConsumer(Destination);
    TextMessage := Consumer.Receive(2500) as ITextMessage;

    CheckEquals('Hello World', TextMessage.Text);
  finally
    Context.Close;
  end;
end;
  • a new connection URL parameter “message.subscription_check=false” allows to subscribe from multiple destinations with a single consumer, by disabling a client-side check subscription id
  • removed support for asynchronous message receive
