Class templates for type classification

template<typename T, typename Tag = null_tag>
struct is_function;

Header

#include <boost/function_types/is_function.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_function<T,Tag>: Predicate value as MPL - Integral Constant
is_function<T,Tag>::value: Constant boolean value

Determines whether a given type is a function, possibly with additional properties as specified by a property tag.

is_function_pointer

template<typename T, typename Tag = null_tag>
struct is_function_pointer;

Header

#include <boost/function_types/is_function_pointer.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_function_pointer<T,Tag>: Predicate value MPL - Integral Constant
is_function_pointer<T,Tag>::value: Constant boolean value

Determines whether a given type is a function pointer, possibly with additional properties as specified by a property tag.

is_function_reference

template<typename T, typename Tag = null_tag>
struct is_function_reference;

Header

#include <boost/function_types/is_function_reference.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_function_reference<T,Tag>: Predicate value MPL - Integral Constant
is_function_reference<T,Tag>::value: Constant boolean value

Determines whether a given type is a function reference, possibly with additional properties as specified by a property tag.

is_member_pointer

template<typename T, typename Tag = null_tag>
struct is_member_pointer;

Header

#include <boost/function_types/is_member_pointer.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_member_pointer<T,Tag>: Predicate value MPL - Integral Constant
is_member_pointer<T,Tag>::value: Constant boolean value

Determines whether a given type is a pointer to member (object or function) type, possibly with additional properties as specified by a property tag.

is_member_object_pointer

template<typename T>
struct is_member_object_pointer;

Header

#include <boost/function_types/is_member_object_pointer.hpp>

T: Type to analyze
is_member_object_pointer<T>: Predicate value MPL - Integral Constant
is_member_object_pointer<T>::value: Constant boolean value

Determines whether a given type is a pointer to member object type.

struct is_member_function_pointer;

Header

#include <boost/function_types/is_member_function_pointer.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_member_function_pointer<T,Tag>: Predicate value MPL - Integral Constant
is_member_function_pointer<T,Tag>::value: Constant boolean value

Determines whether a given type is a member function pointer, possibly with additional properties as specified by a property tag.

is_callable_builtin

template<typename T, typename Tag = null_tag>
struct is_callable_builtin;

Header

#include <boost/function_types/is_callable_builtin.hpp>

is_nonmember_callable_builtin

template<typename T, typename Tag = null_tag>
struct is_nonmember_callable_builtin;

Header

#include <boost/function_types/is_nonmember_callable_builtin.hpp>

T: Type to analyze
Tag: Further properties required for a positive result
is_nonmember_callable_builtin<T,Tag>: Predicate value as MPL - Integral Constant
is_nonmember_callable_builtin<T,Tag>::value: Constant boolean value
