## Detailed Description

the major class used for locale generation

This class is used for specification of all parameters required for locale generation and caching. This class const member functions are thread safe if locale class implementation is thread safe.

Examples:

  boundary.cpp, calendar.cpp, collate.cpp, conversions.cpp, hello.cpp, wboundary.cpp, wconversions.cpp, and whello.cpp.

## Constructor & Destructor Documentation

boost::locale::generator::generator | ( |  | ) |

Create new generator using global localization_backend_manager

boost::locale::generator::generator | ( | localization_backend_manager const & |  | ) |

Create new generator using specific localization_backend_manager

## Member Function Documentation

void boost::locale::generator::add_messages_domain | ( | std::string const & | domain | ) |

Add a new domain of messages that would be generated. It should be set in order to enable messages support.

Messages domain has following format: "name" or "name/encoding" where name is the base name of the "mo" file where the catalog is stored without ".mo" extension. For example for file `/usr/share/locale/he/LC_MESSAGES/blog`.mo it would be `blog`.

You can optionally specify the encoding of the keys in the sources by adding "/encoding_name" For example blog/cp1255.

If not defined all keys are assumed to be UTF-8 encoded.

Note:
  When you select a domain for the program using dgettext or message API, you do not specify the encoding part. So for example if the provided domain name was "blog/windows-1255" then for translation you should use dgettext("blog","Hello")

void boost::locale::generator::add_messages_path | ( | std::string const & | path | ) |

Add a search path where dictionaries are looked in.

Note:

- Under the Windows platform the path is treated as a path in the locale's encoding so if you create locale "en_US.windows-1251" then path would be treated as cp1255, and if it is en_US.UTF-8 it is treated as UTF-8. File name is always opened with a wide file name as wide file names are the native file name on Windows.

- Under POSIX platforms all paths passed as-is regardless of encoding as narrow encodings are the native encodings for POSIX platforms.

void boost::locale::generator::categories | ( | locale_category_type | cats | ) |

Set types of facets that should be generated, default all

locale_category_type boost::locale::generator::categories | ( |  | ) | const

Get types of facets that should be generated, default all

character_facet_type boost::locale::generator::characters | ( |  | ) | const

Get the characters type for which the facets should be generated, default all supported

void boost::locale::generator::characters | ( | character_facet_type | chars | ) |

Set the characters type for which the facets should be generated, default all supported

void boost::locale::generator::clear_cache | ( |  | ) |

Remove all cached locales

void boost::locale::generator::clear_domains | ( |  | ) |

Remove all added domains from the list

void boost::locale::generator::clear_options | ( |  | ) |

Clear backend specific options

void boost::locale::generator::clear_paths | ( |  | ) |

Remove all added paths

std::locale boost::locale::generator::generate | ( | std::locale const & | base,
|  | std::string const & | id |
| ) |  |  | const

Generate a locale with id id. Use base as a locale to which all facets are added, instead of std::locale::classic().

std::locale boost::locale::generator::generate | ( | std::string const & | id | ) | const

Generate a locale with id id

void boost::locale::generator::locale_cache_enabled | ( | bool | on | ) |

Turn locale caching ON

bool boost::locale::generator::locale_cache_enabled | ( |  | ) | const

Get locale cache option

std::locale boost::locale::generator::operator() | ( | std::string const & | id | ) | const`[inline]`

Shortcut to generate(id)

void boost::locale::generator::set_default_messages_domain | ( | std::string const & | domain | ) |

Set default message domain. If this member was not called, the first added messages domain is used. If the domain domain is not added yet it is added.

void boost::locale::generator::set_option | ( | std::string const & | name,
|  | std::string const & | value |
| ) |  |  |

Set backend specific option

bool boost::locale::generator::use_ansi_encoding | ( |  | ) | const

Check if by default ANSI encoding is selected or UTF-8 onces. The default is false.

void boost::locale::generator::use_ansi_encoding | ( | bool | enc | ) |

Select ANSI encodings as default system encoding rather then UTF-8 by default under Windows.

The default is the most portable and most powerful encoding, UTF-8, but the user can select "system" one if dealing with legacy applications
