A complete example

The following example illustrates the implementation and use of initializers and destructors from the C++ bindings. The first part shows the IDL for three classes with initializers. For variety, some of the classes use callstyle OIDL and others use callstyle IDL.

#include <somobj.idl>

interface A : SOMObject {
        readonly attribute long a;
        implementation {
                releaseorder: _get_a;
                functionprefix = A;
                somDefaultInit: override, init;
                somDestruct: override;
                somPrintSelf: override;
        };
};


(null)
interface B : SOMObject {
        readonly attribute long b;
        void BwithInitialValue(inout somInitCtrl ctrl,
                               in long initialValue);
        implementation {
                callstyle = oidl;
                releaseorder: _get_b, BwithInitialValue;
                functionprefix = B;
                BwithInitialValue: init;
                somDefaultInit: override, init;
                somDestruct: override;
                somPrintSelf: override;
        };
};


(null)
interface C : A, B      {
        readonly attribute long c;
        void CwithInitialValue(inout somInitCtrl ctrl,
                               in long initialValue);
        void CwithInitialString(inout somInitCtrl ctrl,
                                in string initialString);
        implementation {
                releaseorder: _get_c, CwithInitialString,
                              CwithInitialValue;
                functionprefix = C;
                CwithInitialString: init;
                CwithInitialValue: init;
                somDefaultInit: override;
                somDestruct: override;
                somPrintSelf: override;
        };
};
