  4. Corba Services Overview of CORBA services. www.assignmentpoint.com

  5. Object Invocation Models Invocation models supported in CORBA. www.assignmentpoint.com

  6. Event and Notification Services (1) The logical organization of suppliers and consumers of events, following the push-style model. www.assignmentpoint.com

  7. Event and Notification Services (2) The pull-style model for event delivery in CORBA. www.assignmentpoint.com

  8. Messaging (1) CORBA's callback model for asynchronous method invocation. www.assignmentpoint.com

  9. Messaging (2) CORBA'S polling model for asynchronous method invocation. www.assignmentpoint.com

  10. Interoperability GIOP message types. www.assignmentpoint.com

  11. Clients Logical placement of interceptors in CORBA. www.assignmentpoint.com

  12. Portable Object Adaptor (1) Mapping of CORBA object identifiers to servants. • The POA supports multiple servants. • The POA supports a single servant. www.assignmentpoint.com

  13. Portable Object Adaptor (2) My_servant *my_object; // Declare a reference to a C++ objectCORBA::Objectid_var oid; // Declare a CORBA identifier my_object = new MyServant; // Create a new C++ objectoid = poa ->activate_object (my_object); // Register C++ object as CORBA OBJECT Changing a C++ object into a CORBA object. www.assignmentpoint.com
