Detailed Description

template<bool condition, typename if_true, typename if_false>
struct itasca::type_selector< condition, if_true, if_false >

Class used to select between two types based on a given condition.

Parameters

condition	Either true or false; determines which specification to use.
if_true	Type to be stored if true.
if_false	Type to be stored if false.

This class uses template metaprogramming to act as an "if" statement to determine whether to use one type or another. If compile-time values such as sizeof(), or simply constants, are solely involved in condition, this can be evaluated at compile time.
