The Ref library is a small library that is useful for passing references
to function templates (algorithms) that would usually take copies of their
arguments. It defines the class template reference_wrapper<T>
,
and the two functions ref
and cref
that return instances
of reference_wrapper<T>
.
Refer to Boost.Bind for more information.
namespace std { namespace tr1 { template <class T> class reference_wrapper; template <class T> reference_wrapper<T> ref(T&); template <class T> reference_wrapper<const T> cref(const T&); template <class T> reference_wrapper<T> ref(reference_wrapper<T>); template <class T> reference_wrapper<const T> cref(reference_wrapper<T>); } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_REFERENCE_WRAPPER if your standard library implements this part of TR1.
Standard Conformity: The Boost version of this this component does not currently support function call invocation (2.1.2.4), or derivation from std::unary_function or std::binary_function (2.1.2 paragraphs 3 and 4).
The Boost version is not implicitly convertible to T& as the TR requires.
#include <boost/tr1/memory.hpp>
or
#include <memory>
The shared_ptr
class template
stores a pointer to a dynamically allocated object, typically with a C++
new-expression. The object pointed to is guaranteed to be deleted when the
last shared_ptr
pointing
to it is destroyed or reset. For more information refer to the shared_ptr
and weak_ptr documentation.

Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_SHARED_PTR if your standard library implements this part of TR1.
Standard Conformity: There are no known deviations from the standard when using the Boost version of this component.
#include <boost/tr1/functional.hpp>

#include <functional>
The class template result_of
helps determine the type of a call expression. Given an lvalue f
of type F
and lvalues t1
, t2, ..., tN
of types T1, T2, ..., TN
,
respectively, the type result_of<F(T1, T2, ..., TN)>::type
defines the result type of the expression f(t1, t2, ...,tN)
. The implementation permits the type F
to be a function pointer, function reference,
member function pointer, or class type. For more information refer
to the Boost.Utility documentation.
namespace std { namespace tr1 { template <class T> struct result_of { typedef unspecified type; }; } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_RESULT_OF if your standard library implements this part of TR1.
Standard Conformity: No known problems.
#include <boost/tr1/functional.hpp>
or
#include <functional>
std::tr1::mem_fn
is a generalization of the standard functions std::mem_fun
and std::mem_fun_ref
. It supports member function
pointers with more than one argument, and the returned function object can
take a pointer, a reference, or a smart pointer to an object instance as
its first argument. mem_fn
also supports pointers to data members by treating them as functions taking
no arguments and returning a (const) reference to the member. For more information
refer to the Boost.Mem_fn documentation.
namespace std { namespace tr1 { template <class R, class T> unspecified mem_fn(R T::* pm); } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_MEM_FN if your standard library implements this part of TR1.
Standard Conformity: The Boost implementation
does not produce functors that inherit from std::unary_function
or std::binary_function
, nor does it function correctly
with pointers to volatile member functions (these should be extremely rare
in practice however).
#include <boost/tr1/functional.hpp>
or
#include <functional>
std::tr1::bind
is a generalization of the standard functions std::bind1st
and std::bind2nd
. It supports arbitrary function
objects, functions, function pointers, and member function pointers, and
is able to bind any argument to a specific value or route input arguments
into arbitrary positions. bind
does not place any requirements on the function object; in particular, it
does not need the result_type
,
first_argument_type
and
second_argument_type
standard
typedefs. For more information refer to the Boost.Bind
documentation.
namespace std { namespace tr1 { // [3.6] Function object binders template<class T> struct is_bind_expression; template<class T> struct is_placeholder; template<class F, class T1, ..., class Tn > unspecified bind(F f, T1 t1, ..., Tn tn ); template<class R, class F, class T1, ..., class Tn > unspecified bind(F f, T1 t1, ..., Tn tn ); namespace placeholders { // M is the implementation-defined number of placeholders extern unspecified _1; extern unspecified _2; . . . extern unspecified _M; } } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_BIND if your standard library implements this part of TR1.
Standard Conformity: The traits classes
is_placeholder
and is_bind_expression
are not supported by
the Boost implementation.
The named return value syntax isn't supported if the object being bound is a function pointer, for example:
std::tr1::bind(&my_proc, arg1, arg2 /* etc */); // works OK. std::tr1::bind<double>(&my_proc, arg1, arg2 /* etc */); // causes compiler error. std::tr1::bind<double>(my_function_object, arg1, arg2 /* etc */); // works OK.
On the other hand, the Boost implementation does work with pointers to overloaded functions, and optionally with function pointers with non-standard calling conventions.
#include <boost/tr1/functional.hpp>
or
#include <functional>
The polymorphic function wrappers are a family of class templates that may be used as a generalized callback mechanism. A polymorphic function wrapper shares features with function pointers, in that both define a call interface (for example a function taking two integer arguments and returning a floating-point value) through which some arbitrary code may be called. However a polymorphic function wrapper can call any callable object with a compatible call signature, this could be a function pointer, or it could be a function object produced by std::tr1::bind, or some other mechanism. For more information see the Boost.Function documentation.
namespace std { namespace tr1 { // [3.7] polymorphic function wrappers class bad_function_call; template<class Function> class function; template<class Function> void swap(function<Function>&, function<Function>&); template<class Function1, class Function2> void operator==(const function<Function1>&, const function<Function2>&); template<class Function1, class Function2> void operator!=(const function<Function1>&, const function<Function2>&); template <class Function> bool operator==(const function<Function>&, unspecified-null-pointer-type ); template <class Function> bool operator==(unspecified-null-pointer-type , const function<Function>&); template <class Function> bool operator!=(const function<Function>&, unspecified-null-pointer-type ); template <class Function> bool operator!=(unspecified-null-pointer-type , const function<Function>&); } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_FUNCTION if your standard library implements this part of TR1.
Standard Conformity: The Boost version of
std::tr1::function
lacks the member function target_type()
and does not inherit from std::unary_function
or std::binary_function
when applicable. The member
function target() can only access pointer-to-member targets when they have
been wrapped in mem_fn.
#include <boost/tr1/type_traits.hpp>
or
#include <type_traits>
Type traits enable generic code to access the fundamental properties of a type, to determine the relationship between two types, or to transform one type into another related type. For more information refer to the Boost.Type_traits documentation.
namespace std { namespace tr1 { template <class T, T v> struct integral_constant; typedef integral_constant<bool, true> true_type; typedef integral_constant<bool, false> false_type; // [4.5.1] primary type categories: template <class T> struct is_void; template <class T> struct is_integral; template <class T> struct is_floating_point; template <class T> struct is_array; template <class T> struct is_pointer; template <class T> struct is_reference; template <class T> struct is_member_object_pointer; template <class T> struct is_member_function_pointer; template <class T> struct is_enum; template <class T> struct is_union; template <class T> struct is_class; template <class T> struct is_function; // [4.5.2] composite type categories: template <class T> struct is_arithmetic; template <class T> struct is_fundamental; template <class T> struct is_object; template <class T> struct is_scalar; template <class T> struct is_compound; template <class T> struct is_member_pointer; // [4.5.3] type properties: template <class T> struct is_const; template <class T> struct is_volatile; template <class T> struct is_pod; template <class T> struct is_empty; template <class T> struct is_polymorphic; template <class T> struct is_abstract; template <class T> struct has_trivial_constructor; template <class T> struct has_trivial_copy; template <class T> struct has_trivial_assign; template <class T> struct has_trivial_destructor; template <class T> struct has_nothrow_constructor; template <class T> struct has_nothrow_copy; template <class T> struct has_nothrow_assign; template <class T> struct has_virtual_destructor; template <class T> struct is_signed; template <class T> struct is_unsigned; template <class T> struct alignment_of; template <class T> struct rank; template <class T, unsigned I = 0> struct extent; // [4.6] type relations: template <class T, class U> struct is_same; template <class Base, class Derived> struct is_base_of; template <class From, class To> struct is_convertible; // [4.7.1] const-volatile modifications: template <class T> struct remove_const; template <class T> struct remove_volatile; template <class T> struct remove_cv; template <class T> struct add_const; template <class T> struct add_volatile; template <class T> struct add_cv; // [4.7.2] reference modifications: template <class T> struct remove_reference; template <class T> struct add_reference; // [4.7.3] array modifications: template <class T> struct remove_extent; template <class T> struct remove_all_extents; // [4.7.4] pointer modifications: template <class T> struct remove_pointer; template <class T> struct add_pointer; // [4.8] other transformations: template <std::size_t Len, std::size_t Align> struct aligned_storage; } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_TYPE_TRAITS if your standard library implements this part of TR1.
Standard Conformity: No known problems.
#include <boost/tr1/random.hpp>
or
#include <random>
The random number library is devided into three parts: generators, which are nullary functors producing uniform random number distributions. Distributions, which are unary functors that adapt a generator to some specific kind of distribution. And the class template variate_generator which combines a generator with a distribution, to create a new generator. For more information see the Boost.Random documentation.
namespace std { namespace tr1 { // [5.1.3] Class template variate_generator template<class UniformRandomNumberGenerator, class Distribution> class variate_generator; // [5.1.4.1] Class template linear_congruential template<class IntType, IntType a, IntType c, IntType m> class linear_congruential; // [5.1.4.2] Class template mersenne_twister template<class UIntType, int w, int n, int m, int r, UIntType a, int u, int s, UIntType b, int t, UIntType c, int l> class mersenne_twister; // [5.1.4.3] Class template substract_with_carry template<class IntType, IntType m, int s, int r> class subtract_with_carry; // [5.1.4.4] Class template substract_with_carry_01 template<class RealType, int w, int s, int r> class subtract_with_carry_01; // [5.1.4.5] Class template discard_block template<class UniformRandomNumberGenerator, int p, int r> class discard_block; // [5.1.4.6] Class template xor_combine template<class UniformRandomNumberGenerator1, int s1, class UniformRandomNumberGenerator2, int s2> class xor_combine; // [5.1.5] Predefined generators typedef linear_congruential< implementation-defined , 16807, 0, 2147483647> minstd_rand0; typedef linear_congruential< implementation-defined , 48271, 0, 2147483647> minstd_rand; typedef mersenne_twister< implementation-defined , 32, 624, 397, 31, 0x9908b0df, 11, 7, 0x9d2c5680, 15, 0xefc60000, 18> mt19937; typedef subtract_with_carry_01< float, 24, 10, 24> ranlux_base_01; typedef subtract_with_carry_01< double, 48, 10, 24> ranlux64_base_01; typedef discard_block< subtract_with_carry< implementation-defined , (1<<24), 10, 24>, 223, 24> ranlux3; typedef discard_block< subtract_with_carry< implementation-defined, (1<<24), 10, 24>, 389, 24> ranlux4; typedef discard_block< subtract_with_carry_01< float, 24, 10, 24>, 223, 24> ranlux3_01; typedef discard_block< subtract_with_carry_01< float, 24, 10, 24>, 389, 24> ranlux4_01; // [5.1.6] Class random_device class random_device; // [5.1.7.1] Class template uniform_int template<class IntType = int> class uniform_int; // [5.1.7.2] Class bernoulli_distribution class bernoulli_distribution; // [5.1.7.3] Class template geometric_distribution template<class IntType = int, class RealType = double> class geometric_distribution; // [5.1.7.4] Class template poisson_distribution template<class IntType = int, class RealType = double> class poisson_distribution; // [5.1.7.5] Class template binomial_distribution template<class IntType = int, class RealType = double> class binomial_distribution; // [5.1.7.6] Class template uniform_real template<class RealType = double> class uniform_real; // [5.1.7.7] Class template exponential_distribution template<class RealType = double> class exponential_distribution; // [5.1.7.8] Class template normal_distribution template<class RealType = double> class normal_distribution; // [5.1.7.9] Class template gamma_distribution template<class RealType = double> class gamma_distribution; } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_RANDOM if your standard library implements this part of TR1.
Standard Conformity: The Boost implementation has the following limitations:
Note also that most of the Random number generators have been re-implemented as thin wrappers around the Boost versions in order to provide a standard conforming interface (the Boost versions all take an additional, redundant, template parameter, and are initialized by iterators rather than functors).
#include <boost/tr1/tuple.hpp>
or
#include <tuple>
A tuple is a fixed size collection of elements. Pairs, triples, quadruples etc. are tuples. In a programming language, a tuple is a data object containing other objects as elements. These element objects may be of different types. Tuples are convenient in many circumstances. For instance, tuples make it easy to define functions that return more than one value. Some programming languages, such as ML, Python and Haskell, have built-in tuple constructs. Unfortunately C++ does not. To compensate for this "deficiency", the TR1 Tuple Library implements a tuple construct using templates. For more information see the Boost Tuple Library Documentation.

Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_TUPLE if your standard library implements this part of TR1.
Standard Conformity: No known issues for conforming compilers.
#include <boost/tr1/utility.hpp>

The existing class template std::pair, can also be accessed using the tuple interface.

Standard Conformity: No known problems.
#include <boost/tr1/array.hpp>
or
#include <array>
Class template array is a fixed size array that is safer than and no less efficient than a C style array. Class array fulfils almost all of the requirements of a reversible-container (see Section 23.1, [lib.container.requirements] of the C++ Standard). For more information refer to the Boost.Array documentation.

Standard Conformity: No known issues as of Boost-1.34 onwards.
#include <boost/tr1/functional.hpp>
or
#include <functional>
Class template std::hash is a unary-functor that converts some type T into a hash-value, specializations of std::hash are provided for integer, character, floating point, and pointer types, plus the two string types std::string and std::wstring. See the Boost.Hash documentation for more information.
namespace std { namespace tr1 { template <class T> struct hash : public unary_function<T, size_t> { size_t operator()(T val)const; }; // Hash function specializations template <> struct hash<bool>; template <> struct hash<char>; template <> struct hash<signed char>; template <> struct hash<unsigned char>; template <> struct hash<wchar_t>; template <> struct hash<short>; template <> struct hash<int>; template <> struct hash<long>; template <> struct hash<unsigned short>; template <> struct hash<unsigned int>; template <> struct hash<unsigned long>; template <> struct hash<float>; template <> struct hash<double>; template <> struct hash<long double>; template<class T> struct hash<T*>; template <> struct hash<std::string>; template <> struct hash<std::wstring>; } // namespace tr1 } // namespace std
Configuration: Boost.Config should (automatically) define the macro BOOST_HAS_TR1_HASH if your standard library implements this part of TR1.
Standard Conformity: Boost.Hash adds specialisations of std::hash for a wider range of types than those required by TR1: Boost.Hash acts as a testbed for issue 6.18 in the Library Extension Technical Report Issues List.
#include <boost/tr1/regex.hpp>

This library provides comprehensive support for regular expressions, including either iterator or string based matching, searching, search-and-replace, iteration, and tokenization. Both POSIX and ECMAScript (JavaScript) regular expressions are supported. For more information see the Boost.Regex documentation.

The following function templates have additional overloads: arg
, norm
,
conj
, polar
,
imag
, and real
.
The additional overloads are sufficient to ensure:
long double
, then the overload behaves as if
the argument had been cast to std::complex<long double>
.
double
or is an integer type, then the overload behaves as if the argument had
been cast to std::complex<double>
.
float
,
then the overload behaves as if the argument had been cast to std::complex<float>
.
The function template pow
has additional overloads sufficient to ensure, for a call with at least one
argument of type std::complex<T>
:
complex<long double>
or type long double
,
then the overload behaves as if both arguments were cast to std::complex<long double>
complex<double>
, double
,
or an integer type, then the overload behaves as if both arguments were
cast to std::complex<double>
complex<float>
or float
,
then the overload behaves as if both arguments were cast to std::complex<float>
In the following synopsis, Real
is a floating point type, Arithmetic
is an integer or floating point type, and PROMOTE(X1 ... XN)
is the largest floating point type in the
list X1 to XN, after any non-floating point types in the list have been replaced
by the type double
.

atanh
and fabs
are overloaded for arguments of type std::complex<T>
.
These algorithms are entirely classical, and behave as specified in the C99
standard section 7.3.5. See the Boost.Math
documentation for more information.
