toUpperCase abstract method

Converts all characters in this string to upper case.

If the string is already in all upper case, this method returns this.

'alphabet'.toUpperCase(); // 'ALPHABET'
'ABC'.toUpperCase(); // 'ABC'

This function uses the language independent Unicode mapping and thus only works in some languages.

Implementation

// TODO(floitsch): document better. (See EcmaScript for description).
String toUpperCase();
