Member Function Documentation

◆ FindByCode()

CountryCode Dwm::CountryCodes::FindByCode ( const std::string & code ) const

Finds a country code by 2 or 3 letter code.

Returns a filled CountryCode on success, an empty CountryCode on failure.

◆ Read() [1/2]

ssize_t Dwm::CountryCodes::Read ( int fd )

Reads the country codes from a descriptor.

Returns the number of bytes read on success, -1 on failure.

◆ Read() [2/2]

size_t Dwm::CountryCodes::Read ( FILE * f )

Reads the country codes from a FILE.

Returns 1 on success, 0 on failure (fread() semantics).

◆ ReadJson()

bool Dwm::CountryCodes::ReadJson ( const std::string & fileName )

Reads the country codes from a JSON file.

Returns true on success, false on failure.

◆ StreamedLength()

uint32_t Dwm::CountryCodes::StreamedLength ( ) const

Returns the number of bytes that should be written if one of the Write() members is called.

◆ Write() [1/2]

ssize_t Dwm::CountryCodes::Write ( int fd ) const

Writes the country codes to a file descriptor.

Returns the number of bytes written on success, -1 on failure.

◆ Write() [2/2]

size_t Dwm::CountryCodes::Write ( FILE * f ) const

Writes the country codes to a FILE.

Returns 1 on success, 0 on failure (fwrite() semantics).

◆ WriteJson()

bool Dwm::CountryCodes::WriteJson ( const std::string & fileName ) const

Writes the country code to a file in JSON format.
