22.11.2 Client-Side C++ Example for the Asynchronous Method Signatures

   This section shows sample C++ that is generated from the implied-IDL of the previous subsections of Section 22.4, “Section II - Introduction,? on page 22-13. The C++ mapping specifies a generated interface class (stub) on which method invocations are translated into operation requests. It is this class on which the function signatures are generated from their operation declarations in IDL. It is in this class that the async functions signatures are also declared (and implemented). Using the IDL from the example in the previous section the stub class StockManager is generated following the C++ mapping. The following notes apply to this sample generated C++ code:

• Only the generated synchronous and asynchronous method signatures are shown. Vendor-specific constructors, methods, and members are omitted.

• Although optional according to the IDL to C++ language mapping, method signatures are generated as virtual.

• Since optional according to the IDL to C++ language mapping, exception specifications are not included in generated methods.
