Boost Develop Library Documentation

Sort by:
  • Value Initialized: Wrapper for uniform-syntax value initialization, based on the original idea of David Abrahams.
  • Operators: Templates ease arithmetic classes and iterators.
  • Config: Helps Boost library developers adapt to compiler idiosyncrasies; not intended for library users.
  • Timer: Event timer, progress timer, and progress display classes.
  • Integer: The organization of boost integer headers and classes is designed to take advantage of <stdint.h> types from the 1999 C standard without resorting to undefined behavior in terms of the 1998 C++ standard. The header <boost/cstdint.hpp> makes the standard integer types safely available in namespace boost without placing any names in namespace std.
  • Rational: A rational number class.
  • Call Traits: Defines types for passing parameters.
  • Utility: Class noncopyable plus checked_delete(), checked_array_delete(), next(), prior() function templates, plus base-from-member idiom.
  • Type Traits: Templates for fundamental properties of types.
  • Compressed Pair: Empty member optimization.
  • Random: A complete system for random number generation.
  • Functional: The Boost.Function library contains a family of class templates that are function object wrappers.
  • Array: STL compliant container wrapper for arrays of constant size.
  • Graph: The BGL graph interface and graph components are generic, in the same sense as the Standard Template Library (STL).
  • Regex: Regular expression library.
  • Concept Check: Tools for generic programming.
  • Static Assert: Static assertions (compile time assertions).
  • Python: The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler.
  • Property Map: Concepts defining interfaces which map key objects to value objects.
  • Conversion: Polymorphic casts.
  • Lexical Cast: General literal text conversions, such as an int represented a string, or vice-versa.
  • Test: Support for simple program testing, full unit testing, and for program execution monitoring.
  • Pool: Memory pool management.
  • Iterator: The Boost Iterator Library contains two parts. The first is a system of concepts which extend the C++ standard iterator requirements. The second is a framework of components for building iterators based on these extended concepts and includes several useful iterator adaptors.
  • Compatibility: Help for non-conforming standard libraries.
  • CRC: The Boost CRC Library provides two implementations of CRC (cyclic redundancy code) computation objects and two implementations of CRC computation functions. The implementations are template-based.
  • Smart Ptr: Smart pointer class templates.
  • Tokenizer: Break of a string or other character sequence into a series of tokens.
  • Math: Boost.Math includes several contributions in the domain of mathematics: The Greatest Common Divisor and Least Common Multiple library provides run-time and compile-time evaluation of the greatest common divisor (GCD) or least common multiple (LCM) of two integers. The Special Functions library currently provides eight templated special functions, in namespace boost. The Complex Number Inverse Trigonometric Functions are the inverses of trigonometric functions currently present in the C++ standard. Quaternions are a relative of complex numbers often used to parameterise rotations in three dimentional space. Octonions, like quaternions, are a relative of complex numbers.
  • Any: Safe, generic container for single values of different value types.
  • Function: Function object wrappers for deferred calls or callbacks.

  • Bind: boost::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.
  • Math Common Factor: Greatest common divisor and least common multiple.
  • Preprocessor: Preprocessor metaprogramming tools including repetition and recursion.
  • Assert: Customizable assert macros.
  • Lambda: Define small unnamed function objects at the actual call site, and more.
  • IO: Utilities for the standard I/O library.
  • Multi-Array: Boost.MultiArray provides a generic N-dimensional array concept definition and common implementations of that interface.

  • Date Time: A set of date-time libraries based on generic programming concepts.
  • Dynamic Bitset: The dynamic_bitset class represents a set of bits. It provides accesses to the value of individual bits via an operator[] and provides all of the bitwise operators that one can apply to builtin integers, such as operator& and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dynamic_bitset.
  • Format: The format library provides a type-safe mechanism for formatting arguments according to a printf-like format-string.
  • Spirit: LL parser framework represents parsers directly as EBNF grammars in inlined C++.
  • Optional: A value-semantic, type-safe wrapper for representing 'optional' (or 'nullable') objects of a given type. An optional object may or may not contain a value of the underlying type.
  • Interval: Extends the usual arithmetic functions to mathematical intervals.
  • Filesystem: The Boost Filesystem Library provides portable facilities to query and manipulate paths, files, and directories.
  • MPL: The Boost.MPL library is a general-purpose, high-level C++ template metaprogramming framework of compile-time algorithms, sequences and metafunctions. It provides a conceptual foundation and an extensive set of powerful and coherent tools that make doing explict metaprogramming in C++ as easy and enjoyable as possible within the current language.
  • Enable If: Selective inclusion of function template overloads.
  • Variant: Safe, generic, stack-based discriminated union container.
  • Min-Max: Standard library extensions for simultaneous min/max and min/max element computations.

  • Pointer Container: Containers for storing heap-allocated polymorphic objects to ease OO-programming.
  • Iostreams: Boost.IOStreams provides a framework for defining streams, stream buffers and i/o filters.
  • Typeof: Typeof operator emulation.
  • Xpressive: Regular expressions that can be written as strings or as expression templates, and which can refer to each other and themselves recursively with the power of context-free grammars.
  • Foreach: In C++, writing a loop that iterates over a sequence is tedious. We can either use iterators, which requires a considerable amount of boiler-plate, or we can use the std::for_each() algorithm and move our loop body into a predicate, which requires no less boiler-plate and forces us to move our logic far from where it will be used. In contrast, some other languages, like Perl, provide a dedicated "foreach" construct that automates this process. BOOST_FOREACH is just such a construct for C++. It iterates over sequences for us, freeing us from having to deal directly with iterators or write predicates.
