Detailed Description

template<class T>
struct SG::TopBase< T >

Calculate topmost base accessible via SG_BASES that also has a defined CLID.

For example, if we have

SG_BASES(C2, C1);
SG_BASES(C3, C2);

with all three classes having CLIDs defined, then TopBase<C1>::type, TopBase<C2>::type, and TopBase<C3>::type all yield C1.

If, on the other hand, there is no CLID for C2, then TopBase<C3>::type will yield C3.

For the use of this, see the comments for ReadDecorHandleKey.
