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.
Compiler Compatibility: All current compilers are supported by this trait.
Header: #include
<boost/type_traits/is_compound.hpp>
or #include <boost/type_traits.hpp>
Examples:
is_compound<MyClass>inherits fromtrue_type.
is_compound<MyEnum>::typeis the typetrue_type.
is_compound<int*>::valueis an integral constant expression that evaluates to true.
is_compound<int&>::valueis an integral constant expression that evaluates to true.
is_compound<int>::valueis an integral constant expression that evaluates to false.
is_compound<T>::value_typeis the typebool.
