public class LanguageParser
- extends ListParser<java.util.Locale>
LanguageParser is used to parse the HTTP Accept-Language
header. This takes in an Accept-Language
header and parses
it according the RFC 2616 BNF for the Accept-Language
header.
This also has the ability to sequence the language tokens in terms of
the most preferred and the least preferred.
This uses the qvalues outlined by RFC 2616 to order the language tokens
by preference. Typically the language tokens will not have qvalues with
the language. However when a language tag has the qvalue parameter then
this tag will be ordered based on the value of that parameter. A language
tag without the qvalue parameter is considered to have a qvalue of 1 and
is ordered accordingly.

protected java.util.Locale create(char[] text,
int start,
int len)
- This creates a locale object using an offset and a length.
The locale is created from the extracted token and the offset
and length ensure that no leading or trailing whitespace are
within the created locale object.
- Specified by:

- Parameters:
text
- this is the text buffer to acquire the value fromstart
- the offset within the array to take characterslen
- this is the number of characters within the token
