Classes
class	ctti_type_index
	This class is a wrapper that pretends to work exactly like stl_type_index, but does not require RTTI support. More...
class	stl_type_index
	This class is a wrapper around std::type_info, that workarounds issues and provides much more rich interface. More...
class	type_index_facade
	This class takes care about the comparison operators, hash functions and ostream operators. More...

Typedefs
typedef boost::typeindex::stl_type_index	type_index
typedef type_index::type_info_t	type_info
	Depending on a compiler flags, optimal implementation of type_info will be used as a default boost::typeindex::type_info. More...

Functions

Typedef Documentation

typedef boost::typeindex::stl_type_index boost::typeindex::type_index

typedef type_index::type_info_t boost::typeindex::type_info

Depending on a compiler flags, optimal implementation of type_info will be used as a default boost::typeindex::type_info.

Could be a std::type_info, boost::typeindex::detail::ctti_data or some user defined class.

type_info is not copyable or default constructible. It is not assignable too!

Function Documentation

template<class T >

const detail::ctti_data& boost::typeindex::ctti_construct ( )

inline

Helper method for getting detail::ctti_data of a template parameter T.

References n.

template<class Derived , class TypeInfo >

std::size_t boost::typeindex::hash_value ( const type_index_facade< Derived, TypeInfo > &  lhs )

inline

This free function is used by Boost's unordered containers.

Note

<boost/functional/hash.hpp> has to be included if this function is used.

References boost::detail::const.

template<class CharT , class TriatT , class Derived , class TypeInfo >

std::basic_ostream<CharT, TriatT>& boost::typeindex::operator<< ( std::basic_ostream< CharT, TriatT > &  ostr, const type_index_facade< Derived, TypeInfo > &  ind  )

inline

Ostream operator that will output demangled name.

template<class T >

type_index boost::typeindex::type_id ( )

inline

Function to get boost::typeindex::type_index for a type T.

Removes const, volatile && and & modifiers from T.

Example:

type_index ti = type_id<int&>();
std::cout << ti.pretty_name();  // Outputs 'int'

Template Parameters

T	Type for which type_index must be created.

Exceptions

Nothing.

Returns

boost::typeindex::type_index with information about the specified type T.

template<class T >

type_index boost::typeindex::type_id_runtime ( const T &  runtime_val )

inline

Function that works exactly like C++ typeid(rtti_val) call, but returns boost::type_index.

Retunrs runtime information about specified type.

Requirements: RTTI available or Base and Derived classes must be marked with BOOST_TYPE_INDEX_REGISTER_CLASS.

Example:

struct Base { virtual ~Base(){} };
struct Derived: public Base  {};
...
Derived d;
Base& b = d;
type_index ti = type_id_runtime(b);
std::cout << ti.pretty_name();  // Outputs 'Derived'

Parameters

runtime_val

Varaible which runtime type must be returned.

Exceptions

Nothing.

Returns

boost::typeindex::type_index with information about the specified variable.

References boost::typeindex::stl_type_index::type_id_runtime().

template<class T >

type_index boost::typeindex::type_id_with_cvr ( )

inline

Function for constructing boost::typeindex::type_index instance for type T.

Does not remove const, volatile, & and && modifiers from T.

If T has no const, volatile, & and && modifiers, then returns exactly the same result as in case of calling type_id<T>().

Example:

type_index ti = type_id_with_cvr<int&>();
std::cout << ti.pretty_name();  // Outputs 'int&'

Template Parameters

T	Type for which type_index must be created.

Exceptions

Nothing.

Returns

boost::typeindex::type_index with information about the specified type T.
