Function Documentation

basic_message() [1/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const char_type *  id )

inlineexplicit

Create a simple message from 0 terminated string. The string should exist until the message is destroyed. Generally useful with static constant strings

basic_message() [2/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const char_type *  single, const char_type *  plural, int  n  )

inlineexplicit

Create a simple plural form message from 0 terminated strings. The strings should exist until the message is destroyed. Generally useful with static constant strings.

n is the number, single and plural are singular and plural forms of the message

basic_message() [3/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const char_type *  context, const char_type *  id  )

inlineexplicit

Create a simple message from 0 terminated strings, with context information. The string should exist until the message is destroyed. Generally useful with static constant strings

basic_message() [4/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const char_type *  context, const char_type *  single, const char_type *  plural, int  n  )

inlineexplicit

Create a simple plural form message from 0 terminated strings, with context. The strings should exist until the message is destroyed. Generally useful with static constant strings.

n is the number, single and plural are singular and plural forms of the message

basic_message() [5/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const string_type &  single, const string_type &  plural, int  number  )

inlineexplicit

Create a simple plural form message from strings.

n is the number, single and plural are single and plural forms of the message

basic_message() [6/6]

template<typename CharType>

boost::locale::basic_message< CharType >::basic_message ( const string_type &  context, const string_type &  single, const string_type &  plural, int  number  )

inlineexplicit

Create a simple plural form message from strings.

n is the number, single and plural are single and plural forms of the message

convert()

template<typename CharType>

virtual const char_type* boost::locale::message_format< CharType >::convert ( const char_type *  msg, string_type &  buffer  ) const

pure virtual

Convert the string msg to target locale's encoding. If msg is already in target encoding it would be returned otherwise the converted string is stored in temporary buffer and buffer.c_str() is returned.

Note: for char_type that is char16_t, char32_t and wchar_t it is no-op, returns msg

get() [1/2]

template<typename CharType>

virtual const char_type* boost::locale::message_format< CharType >::get ( int  domain_id, const char_type *  context, const char_type *  id  ) const

pure virtual

This function returns a pointer to the string for a message defined by a context and identification string id. Both create a single key for message lookup in a domain defined by domain_id.

If context is NULL it is not considered to be a part of the key

If a translated string is found, it is returned, otherwise NULL is returned

get() [2/2]

template<typename CharType>

virtual const char_type* boost::locale::message_format< CharType >::get ( int  domain_id, const char_type *  context, const char_type *  single_id, int  n  ) const

pure virtual

This function returns a pointer to the string for a plural message defined by a context and identification string single_id.

If context is NULL it is not considered to be a part of the key

Both create a single key for message lookup in a domain defined domain_id. n is used to pick the correct translation string for a specific number.

If a translated string is found, it is returned, otherwise NULL is returned

write()

template<typename CharType>

void boost::locale::basic_message< CharType >::write ( std::basic_ostream< char_type > &  out ) const

inline

Translate message and write to stream out, using imbued locale and domain set to the stream
