Hello. I am trying to understand the following code. When the CTB<CType>::Initialize() member function is called, what object of type vector<CType> is going to have all the items removed? I am not sure why the Initialize function has no argument to specifically tells the clear() function which list to clear. Any ideas? Thanks.

template< class CType >
void CTB<CType>::Initialize(void)
{
vector<CType> ::clear();
}

If clear is not a static method of the vector template, then CTB<CType> must inherit vector<CType> in order for this to work. In other words, CTB<CType> is a vector<CType>, as opposed to CTB<CType> has a vector<CType> member.
