template <class T>
struct is_array : public true_type-or-false_type {};
Inherits: If T is a (possibly cv-qualified) array type then inherits from true_type, otherwise inherits from false_type.
C++ Standard Reference: 3.9.2 and 8.3.4.
Header: #include
<boost/type_traits/is_array.hpp>
or #include <boost/type_traits.hpp>
Compiler Compatibility: All current compilers are supported by this trait.
Examples:
is_array<int[2]>inherits fromtrue_type.
is_array<char[2][3]>::typeis the typetrue_type.
is_array<double[]>::valueis an integral constant expression that evaluates to true.
is_array<T>::value_typeis the typebool.
