MetaUtils_test Class Reference

Description

Test:
verify basic type trait and metaprogramming helpers.
  • marker types to tell which overload the compiler picks
  • simple trait to detect the possibility of a string conversion
  • trait to detect a typelist type

void verify_basicTypeProbing ( )

Test:
demonstrate the basic type trait detection technique:
  • we have two overloads with differing return type
  • we form a function call expression
  • by investigating the return type, we can figure out which overload the compiler picks.
