- [section Introduction]
- ['Boost.Convert] builds on the `boost::lexical_cast` experience and takes those type conversion\/transformation-related ideas further
- * to be applicable to a wider range of conversion-related deployment scenarios,
- * to provide a more flexible, configurable and extendible type-conversion framework,
- * to provide generic consistent behavior,
- * to ['unify and to uniformly deploy] various conversion facilities ['through one consistent interface].
- ['Boost.Convert] provides new and familiar conversion\/transformation-related functionality such as:
- * means to deploy types that do not meet the [@http://en.cppreference.com/w/cpp/named_req/DefaultConstructible ['Default Constructibility]] requirement;
- * four types of the conversion-failure ['detection]:
- * as part of the same process flow -- basic and generic;
- * as a branched process flow -- exception-based and function-based;
- * the choice of immediate or delayed exception-throwing and non-throwing conversion-failure ['processing];
- * flexibility of conversion-failure ['processing] via:
- * an exception thrown;
- * the fallback value returned;
- * the fallback function called;
- * support for standard algorithms.
- ['Boost.Convert] consists of two components:
- * the `boost::convert()` interface;
- * an extendible collection of pluggable converters.
- The `boost::convert()` interface
- * advertises, provides and ensures certain ['consistent behavior];
- * unifies and provides ['one consistent interface] to various conversion facilities.
- The collection of pluggable converters is independent of the `boost::convert()` API facade and is designed to be ['extendible] and extended over time. Currently the following converters are provided:
- * `boost::lexical_cast`-based,
- * `printf/scanf`-based,
- * `strtol`-inspired,
- * `std::stringstream`-based,
- * `boost::spirit`-based.
- The converters provide new and familiar functionality and demonstrate how existing and independent conversion facilities might be incorporated in to the ['Boost.Convert] framework. For example, the `std::stream`-based converter draws on the standard `std::streams` functionality and provides:
- * string-to-type and type-to-string conversions;
- * formatting support (`std::ios`-based precision, base, upper/lower-case, scientific, etc.);
- * support for different `locale`s;
- * `char` and `wchar_t` support.
