>    Affects Versions: 0.2, 0.3
>         Environment: Cygwin 1.7.1 on Windows XP SP3, Thrift 0.2.0 & r760184 & Trunk 
>            Reporter: Tim Wilson-Brown
>            Priority: Minor

>   Original Estimate: 24h

> The C++ Compiler currelty emits most functions in the *Client class as non-virtual.
> This makes it impossible to subclass the generated class and override its functions.
> A workaround is to inherit from the interface class *If, override the functions, and use them to call a *Client class member pointer.
> But this can be cumbersome in some situations.
> I propose to add a virtual option to the C++ compiler that emits function declarations as virtual.
> I have attached a patched version of t_cpp_generator.cc from Thrift 0.2.0 - I can work out how to turn it into a patch file if needed.
> Is this worth merging into the trunk?
