parsing the query string - newbie question

[Pete]

in the handlePost method of my resource class, request.getEntity().getText()
returns me a query string like a=b&c=d&e=f etc. is there anything restlet has to
parse such query string and return map or something? I see that the only way you
can get you data from org.restlet.data.Request is Representation which developer
then have to parse it to put it in domain object.
