template <class T>
struct is_pointer : public true_type-or-false_type
{};
Inherits: If T is a (possibly cv-qualified) pointer type (includes function pointers, but excludes pointers to members) then inherits from true_type, otherwise inherits from false_type.
C++ Standard Reference: 3.9.2p2 and 8.3.1.
Header: #include
<boost/type_traits/is_pointer.hpp>
or #include <boost/type_traits.hpp>
Compiler Compatibility: All current compilers are supported by this trait.
Examples:
is_pointer<int*>
inherits fromtrue_type
.
is_pointer<char* const>::type
is the typetrue_type
.
is_pointer<int (*)(long)>::value
is an integral constant expression that evaluates to true.
is_pointer<int (MyClass::*)(long)>::value
is an integral constant expression that evaluates to false.
is_pointer<int (MyClass::*)>::value
is an integral constant expression that evaluates to false.
is_pointer<T>::value_type
is the typebool
.
