Callback Signature List

List of all callback defined by JavaMqMsgque

The callback have to be a class with an interface like jvmsgque.mqmsgque.MqServiceIF

There a two different types of callback:

1. A callback used to define a context
   • interface: jvmsgque.mqmsgque.IServerSetup
   • interface: jvmsgque.mqmsgque.IServerCleanup
   • interface: jvmsgque.mqmsgque.IBgError
   • interface: jvmsgque.mqmsgque.IEvent
2. A callback used to define a service
   • ctx.ServiceCreate(String token, MqServiceIF callback)
   • ctx.SendEND_AND_CALLBACK(String token, MqServiceIF callback, ?long timeout = MkTimeoutE.DEFAULT.get()?)
   • ctx.SendEND_AND_SUB(String token, MqServiceIF callback, ?long timeout = MkTimeoutE.DEFAULT.get()?)

Callback signature

The callback in an interface using a single virtual function called Callback.

 
/* LABEL-NO */
package jvmsgque.mqmsgque;
 
public interface MqServiceIF {
  void Callback (MqContextC ctx);
}
 

Example from MyServer.java → using MqServiceCreate with callback jvmsgque::mqmsgque::MqServiceIF

package example;

import jvmsgque.mkkernel.*;
import jvmsgque.mqmsgque.*;

// package-item
final class MyServer extends MqContextC implements IServerSetup {

  // Factory Constructor
  public MyServer(MqContextC tmpl) {
    super(tmpl);
  }

  // service to serve all incoming requests for token "HLWO"
  class MyFirstCallback implements MqServiceIF {
    public void Callback(MqContextC ctx) {
      SendSTART();
      SendSTR(ReadSTR() + " World");
      SendRETURN();
    }
  }

  // define a service as link between the token "HLWO" and the class "MyFirstService"
  public void ServerSetup() {
    ServiceCreate("HLWO", new MyFirstCallback());
  }

  // -------------------------------------------------------------

  // package-main
  public static void main(String[] argv) {
  
    // create the "MyServer" factory… and return the initial (top) object
    MqContextC srv = MqFactoryC.Add(MyServer.class).New();

    try {
      srv.LinkCreate(argv);
      srv.ProcessEvent(MqWaitOnEventE.FOREVER);
    } catch (Throwable e) {
      srv.ErrorCatch(e);
    }
    srv.Exit();
  }
}
