/**
 * A DCOPRef(erence) encapsulates a remote DCOP object as a triple
 * <app,obj,type> where type is optional. It allows for calling and
 * passing DCOP objects.
 *
 * A DCOP reference makes it possible to return references to other DCOP
 * objects in a DCOP interface, for example in the method
 * giveMeAnotherObject() in an interface like this:
 *
 * \code
 *	class Example : public DCOPObject
 *	{
 *	   K_DCOP
 *	...
 *	k_dcop:
 *	   DCOPRef giveMeAnotherObject();
 *	   int doSomething( TQString, float, bool );
 *	   ASYNC pingMe( TQCString message );
 *	   UserType userFunction( UserType );
 *	};
 * \endcode
 *
 * In addition, the reference can operate as a comfortable generic
 * stub to call remote DCOP objects in cases where no DCOPStub is
 * available. The advantage of using DCOPRef instead of the low-level
 * functions DCOPClient::call() and DCOPClient::send() are the nicer
 * syntax and the implicit runtime error checking.
 *
 * Say you want to call the method "doSomething" from the above
 * interface on an object called "example" that lives in application
 * "foo". Using DCOPRef, you would write
 *
 * \code
 *	DCOPRef example( "foo", "example" );
 *	int result = example.call( "doSomething", TQString("Hello World"), (float)2.5, true );
 * \endcode
 *
 * If it is important for you to know whether the call succeeded or
 * not, you can use the slightly more elaborate pattern:
 *
 * \code
 *	DCOPRef example( "foo", "example" );
 *	DCOPReply reply = example.call( "doSomething", TQString("Hello World"), (float)2.5, true );
 *	if ( reply.isValid() ) {
 *	    int result = reply;
 *	    // ...
 *	}
 * \endcode
 *
 * Note that you must pass a TQString for the first argument. If you use a
 * regular char pointer, it will be converted to a TQCString.
 *
 * For curiosity, here is how you would achieve the exactly same
 * functionality by using DCOPClient::call() directly:
 *
 * \code
 *    TQByteArray data, replyData;
 *    TQCString replyType;
 *    TQDataStream arg( data, IO_WriteOnly );
 *    arg << TQString("hello world" ), (float) 2.5 << true;
 *    if ( DCOPClient::mainClient()->call( app, obj,
 *			     "doSomething(TQString,float,bool)",
 *			     data, replyType, replyData ) ) {
 *	if ( replyType == "int" ) {
 *	    int result;
 *	    TQDataStream reply( replyData, IO_ReadOnly );
 *	    reply >> result;
 *	    // ...
 *	}
 *    }
 * \endcode
 *
 * As you might see from the code snippet, the DCOPRef has to "guess"
 * the names of the datatypes of the arguments to construct a dcop
 * call. This is done through global inline overloads of the
 * dcopTypeName function, for example
 *
 * \code
 *	inline const char* dcopTypeName( const TQString& ) { return TQSTRING_OBJECT_NAME_STRING; }
 * \endcode
 *
 * If you use custom data types that do support TQDataStream but have
 * no corresponding dcopTypeName overload, you can either provide such
 * an overload or use a DCOPArg wrapper that allows you to specify the type.
 *
 * \code
 *	UserType userType;
 *	DCOPReply reply = example.call( "userFunction", DCOPArg( userType, "UserType" ) );
 * \endcode
 *
 * Similar, when you retrieve such a data type, you can use an
 * explicit call to DCOPReply::get():
 *
 * \code
 *	UserType userType;
 *	reply.get( userType, "UserType" );
 * \endcode
 *
 * The function send() works very similar to call(), only that it
 * returns a simple bool on whether the signal could be sent or not:
 *
 * \code
 *	if ( example.send( "pingMe", "message" ) == false )
 *	   tqWarning("could not ping example" );
 * \endcode
 *
 * A DCOP reference operates on DCOPClient::mainClient(), unless you
 * explicitly specify another client with setDCOPClient().
