Class LanguageDecoratorMapper
java.lang.Object
 com.opensymphony.module.sitemesh.mapper.AbstractDecoratorMapper
com.opensymphony.module.sitemesh.mapper.LanguageDecoratorMapper
- All Implemented Interfaces:
- DecoratorMapper
public class LanguageDecoratorMapper - extends AbstractDecoratorMapper
The LanguageDecoratorMapper can determine the preferred language set in the
browser requesting a page, and map to a suitable Decorator (using the
"Accept-Language" HTTP header).
This can be useful for supplying different versions of the same content
for different languages.
When LanguageDecoratorMapper is in the chain, it will request the appropriate Decorator
from its parent. It will then add an extention to the filename of the Decorator, and
if that file exists it shall be used as the Decorator instead. For example, if the
Decorator path is /blah.jsp and the detected preferred language is en,
the path /blah-en.jsp shall be used.
The language mappings are configured by passing properties with match. as a prefix.
For example: 'match.en'=engl , 'match.nl'=dutch .
