The goal of writing this code was to get a better understanding of partial template specialization. I'm trying to partial specialize the class Vector with three different bools.
I have an enum(for my bool) defined as:
enum MY_BOOL
{
YES,
NO,
MAYBE
};
For my primary template class I have
template<class A,MY_BOOL,class B>
class Vector{};
And the partial specialization class I have is
template<MY_BOOL b>
class Vector<A,YES,B>{};
The compiler is complaining that A and B are undeclared identifiers and that the partial specialized Vector has too few arguments. Doesn't complain about 'YES' This confuses me because A and B were already defined in the primary template class. I shouldn't need to put them back in the parameter list of the partial specialized class because the point of that parameter list is to only have the variables that I want specialized.
In
template<MY_BOOL b>
class Vector<A,YES,B>{};
Since A and B aren't specified, you get a compiler error. It is not going to use the A and B from the primary template, it will only use the types/value defined in the specialization.
Since you want a specialization for each of the enum values you can do that like
template<class A,MY_BOOL,class B>
class Vector {};
template<class A, class B>
class Vector<A, YES, B>{ /* YES stuff */ };
template<class A, class B>
class Vector<A, NO, B>{ /* NO stuff */ };
template<class A, class B>
class Vector<A, MAYBE, B>{ /* MAYBE stuff */ };
And now you have a specialization for each of the enumerations.
