| <p>The ENABLE_IF_* macros are used to 'enable' - i.e. to make available to the compiler - a method only if a type parameter belongs to the set described by each macro. Each macro takes the return type of the method as an argument (a requirement of the underlying type trait template that implements this logic). Usage: template <typename t>=""> <a class="el" href="template-util_8h.html#a7e134cd6c516e8dfb9ee0392c3a86a48">ENABLE_IF_ARITHMETIC(T, T)</a> foo(T arg) { return arg + 2; } Enables a method only if 'type_param' is arithmetic, that is an integral type or a floating-point type </p> |
