[luabind] Speed optimization question

[Dmitriy I. <ias...@gs...>]

Hello,

I'd like to ask if there any way in C++ to find out if derived in LUA
class overrode the particular class member (having an instance of this
class)?

Consider we exported via luabind to LUA class A with the corresponding
class wrapper as described in manual. We also exported to LUA
container class C, which holds instances of the class A. Then we
create in LUA new class B, which is derived from class A, and overrode
several members of the class A. Then we create an instance b of the
newly created class B and pass it back to the C++ to the instance c of
the class C via function that transfers an ownership to the b from LUA
to C++. Every time c updates, it goes through the instances of the
class A it holds and call their virtual function "update". It works
ok, but when we call "update" of the b, luabind tries to find if B
overrode virtual function update, though, since we have an instance of
the class, we can compute this just one time. Is this possible and
safe?
