types_are_equal< T, U > Struct Template Reference

#include <deal.II/base/template_constraints.h>

Inherits is_same< T, U >.

Detailed Description

template<typename T, typename U>
struct types_are_equal< T, U >

A type that can be used to determine whether two types are equal. It allows to write code like

template <typename T>
void Vector<T>::some_operation () {
  if (std::is_same<T,double>::value == true)
    call_some_blas_function_for_doubles;
  else
    do_it_by_hand;
}

This construct is made possible through the existence of a partial specialization of the class for template arguments that are equal.

Deprecated:

Use the standard library type trait std::is_same instead of this class.
