Detailed Description

template<class Base, size_t BufferSize = sizeof(Base)>
struct EsfFixedSizePolymorphicHolder< Base, BufferSize >::Compatibility

Checks if instances of Derived can be stored in this holder.

If any member of this class is false, then instances of Derived cannot be stored in this holder. These checks are made public for testing.

bool EsfFixedSizePolymorphicHolder< Base, BufferSize >::Compatibility::HasBaseAtSameAddress ( const Derived &  derived )

static

Verifies that a Derived instance has the same address as its Base.

This check would fail for certain cases of multiple-inheritance. C++ does not currently allow checking this at compile-time, so this check can only happen at runtime.
