is_compound

template <class T>
struct is_compound : public true_type-or-false_type {};

Inherits: If T is a (possibly cv-qualified) compound type then inherits from true_type, otherwise inherits from false_type. Any type that is not a fundamental type is a compound type (see also is_fundamental).

C++ Standard Reference: 3.9.2.

Header: #include <boost/type_traits/is_compound.hpp> or #include <boost/type_traits.hpp>

Examples:

is_compound<MyClass> inherits from true_type.

is_compound<MyEnum>::type is the type true_type.

is_compound<int*>::value is an integral constant expression that evaluates to true.

is_compound<int&>::value is an integral constant expression that evaluates to true.

is_compound<int>::value is an integral constant expression that evaluates to false.

is_compound<T>::value_type is the type bool.
