Static ORB Proxy and Skeleton for ACDK

With th acdkmc plugin static skeleton/proxies can be created from ACDK classes.

Please refer to the AddressServer and AddressClient project in the acdkx_orb package.

Generate static skeletons and proxy

The project acdkx_orb_mc project contains a acdkmc plugin to generate static proxies for CORBA.

Sample:



ACDK_DECL_INTERFACE(AdressBook);

/** 
  call the acdk plugin OrbDispatchAttribute to
  generate the static CORBA proxy
*/
ACDK_CLASSATTRIBUTE(acdkx.orb.mc.OrbDispatchAttribute())
class AdressBook 
: implements ::org::omg::CORBA::portable::InvokeHandler
{
  ACDK_WITH_METAINFO(AdressBook)
public:
  ACDK_CORBA_INTERFACE(AdressBook)
public:
  virtual void ping() = 0;
  virtual void testArray(IN(RintArray) longs, OUT(RStringArray) strings) = 0;
  virtual RAdressInfo getAddressInfoA(RString name) = 0;
  virtual void getAddressInfoB(RString name, OUT(RAdressInfo) adressinfo) = 0;
  virtual void setAddressInfo(RString name, IN(RAdressInfo) adressinfo) = 0;
  virtual RAdressInfoArray getAllAdressInfos() = 0;
  virtual void setOtherAdressBook(IN(RAdressBook) other) = 0;
  virtual void getOtherAdressBook(OUT(RAdressBook) other) = 0;
};

This will generate AdressBook_Skel class and the AdressBook::_invoke() in the *_metainf_ext.cpp file.

Implement the server object


class AdressBookImpl
: extends ::acdkx::orb::ServerDelegate,
  implements AdressBook
{
  // implementation of the interface
};

start the server


    RORB orb = ORB::init();
    RAdressBookImpl adressimpl = new AdressBookImpl();
    orb->impl_is_ready((::acdk::lang::RObject)adressimpl);

    RString ostr = orb->object_to_string((::org::omg::CORBA::RObject)adressimpl);
    {
      RString fname = "./AdressBook.ref";
      ::acdk::io::FileWriter f(fname);
      f.write(ostr->getBytes());
      System::out->println(ostr);
    }
    orb->run();

Implement the client


RString refid;
RString fname = "./AdressBook.ref";
::acdk::io::InputReader f(new ::acdk::io::FileReader(fname));
refid = f.readString();
System::out->println("Calling refid: " + refid);
RAdressBook obj = (RAdressBook)orb->string_to_object(refid); // get the object
obj->ping(); // call the server object.

Using ACDK as CORBA value type

ACDK_DECL_CLASS(AdressInfo);
// next attribute gives a hint, that AdressInfo should be uses // as structure, which will be transfered as value ACDK_CLASSATTRIBUTE(acdk.tools.mc.StringTagAttribute("acdkx_orb_StructType")) class AdressInfo : extends ::acdk::lang::Object { ACDK_WITH_METAINFO(AdressInfo) public:
AdressInfo() : Object() { } RString name;
RString street;
int streetnumber;
RString toString() { return "name=[" + name + "]; street=[" + street + RString("]; streetnumber=[") + streetnumber + "];";
} };
