Function Documentation

template<class I>

bool isValidInterface

(

I *

i

)

[inline]

Templated function that throws an exception if the version if the interface implemented by the object behind the interface is incompatible.

This is the case if the major version differs or that the minor version of the client is bigger than of the implementer.

[inline]

Small function to be used instead of the construct (void**)&pointer, which produces, on gcc 4.1 optimized, the warning warning: dereferencing type-punned pointer will break strict-aliasing rules The assempler code produced is equivalent to the one with the direct cast.

The function can be used als to replace the construct (IInterface *&)m_MySvc. Replacement rules:

(void**)&pointer	pp_cast<void>(&pointer)
(IInterface *&)m_mySvc	*pp_cast<IInterface>(&m_mySvc)
