adding LIMIT to a jena query or chanining the existing limit bound

[Soheila Dehghanzadeh]

Hi All, 

I'm trying to manipulate my sparql query by adding a LIMIT or changing the 
existing LIMIT value before i submit it to a remote sparql endpoint.JENA-228 
proposed a similar idea and Andy suggested a solution "to wrap a (limit) 
algebra operator around the execution". i'm not sure how it can be done given 
that there is no OPlimit operator whatsoever. does any body have any idea of 
how to implement it?
Thanks.-Soheila
