### disjunction

    template<class... T>
    struct disjunction;

Inherits: Inherits from the first type `U` in the list for which `bool(U::value)` is `true`, or the last type in the list if there is no such type. If `sizeof...(T)` is `0` then inherits from `false_type`.

Header: `#include <boost/type_traits/disjunction.hpp>`

Compiler Compatibility: All current compilers are supported by this trait. In the absence of variadic-template support, `disjunction` has only 2 parameters.

Examples:

> Given: `template<int N> struct Int { static const int value = N };`

> `disjunction<>` inherits from `false_type`.

> `disjunction<Int<1> >` inherits from `Int<1>`.

> `disjunction<Int<1>, Int<2>, Int<3> >` inherits from `Int<1>`.

> `disjunction<Int<0>, Int<2>, Int<3> >` inherits from `Int<2>`.
