Detailed Description

RWUIsoLanguageList constructs iterators that provide access to the static list of ISO 639 language codes recognized by the Internationalization Module. The list of language codes may be found at http://www.loc.gov/standards/iso639-2/php/code_list.php. The Internationalization Module does not recognize deprecated codes.

The methods are all static, because there is only one list of language codes. The iterator types are all constant, because the list is immutable. RWUIsoLanguageList may also be instantiated to produce an object that mimics a true collection.

Example

#include <rw/i18n/RWUIsoLanguageList.h>
#include <iostream>
 
int main() {
  // Iterate over the list of language codes and write
  // them to std::cout, obtaining iterators from the
  // static RWUIsoLanguageList begin() and end() methods.
  RWUIsoLanguageList::const_iterator iter;
  for (iter = RWUIsoLanguageList::begin();
       iter != RWUIsoLanguageList::end(); ++iter) {
    std::cout << *iter << std::endl;
  }
 
  // Iterate over the list of language codes again, obtaining
  // iterators from an RWUIsoLanguageList object.
  RWUIsoLanguageList list;
  for (iter = list.begin(); iter != list.end(); ++iter) {
    std::cout << *iter << std::endl;
  }
 
  return 0;
}

Member Typedef Documentation

const_iterator

typedef const char* const* RWUIsoLanguageList::const_iterator

A type that provides a const random-access iterator over the elements in the language list.

const_reverse_iterator

typedef std::reverse_iterator<const_iterator> RWUIsoLanguageList::const_reverse_iterator

A type that provides a const random-access, reverse-order iterator over the elements in the language list.

iterator

typedef const char* const* RWUIsoLanguageList::iterator

A type that provides a random-access iterator over the elements in the language list.

reverse_iterator

typedef std::reverse_iterator<iterator> RWUIsoLanguageList::reverse_iterator

A type that provides a random-access, reverse-order iterator over the elements in the language list.
