As previously stated, there is no requirement that the ODL code expressing the mapped Automation interface actually exist.
Other equivalent expressions of Automation interfaces, such as the contents of a Type Library, may be used. Moreover, there
is no requirement that OMG IDL code corresponding to the CORBA View Interface be generated.
However, ODL is the appropriate medium for describing an Automation interface, and OMG IDL is the appropriate medium for describing
a CORBA View Interface. Therefore, we provide the following ODL code to describe an Automation interface, that exercises all
of the Automation base data types in the roles of properties, method [in] parameter, method [out] parameter, method [inout]
parameter, and return value. The ODL code is followed by OMG IDL code describing the CORBA View Interface, which would result
from a conformant mapping.

The corresponding OMG IDL is as follows.
// OMG IDL interface MyModule_TypesTest
{

shortTest; attribute string stringTest; attribute double dateTest; attribute COM::Currency currencyTest;

19.9.11 Mapping for Object References
The mapping of an object reference as a parameter or return value can be fully expressed by the following OMG IDL and ODL
code. The ODL code defines an interface “Simple? and another interface that references Simple as an “in? parameter, an “out?
parameter, an “inout? parameter, and as a return value. The OMG IDL code describes the CORBA View Interface that results from
a proper mapping.
// ODL[odl, dual, uuid(...)]interface DIMyModule_Simple: IDispatch{
[propget] HRESULT shortTest([retval, out] short * val);[propput] HRESULT shortTest([in] short sshortTest);}
[odl, dual, uuid(...)]interface DIMyModule_ObjRefTest: IDispatch{
[propget] HRESULT simpleTest([retval, out]DIMyModule_Simple ** val); [propput] HRESULT simpleTest([in] DIMyModule_Simple*pSimpleTest);
HRESULT simpleOp([in] DIMyModule_Simple *inTest, [out] DIMyModule_Simple **outTest, [in,out]DIMyModule_Simple **inoutTest,[retval, out] DIMyModule_Simple **val);
}
The OMG IDL code for the CORBA View Dispatch Interface is as follows.
// OMG IDL // A simple object we can use for testing object references interface MyModule_Simple {
attribute short shortTest;};
interface MyModule_ObjRefTest
{ attribute MyModule_Simple simpleTest; MyModule_Simple simpleOp(in MyModule_Simple inTest,
out MyModule_Simple outTest, inout MyModule_Simple inoutTest); };
