how to serialize function depending on what instance of object calls it, if same instance call in a thread then do serialize else not
- by LondonDreams
I have a function which fetches and updates some record from db and I am trying to make sure each if the function is called by same instance of object(same Or different thread) then function should behave synchronized else its a call from different object instance function need not to be synchronized.
I have tried it use a lock per client. That is, instead of synchronizing the method directly using explicit locking through lock objects using Map.
function is like :-
getAndUpdateMyHitCount(myObjId){
//go to db and get unique record by myObjId
//fetch value , increment , save update
}
And this function may get call is same thread by different Or same object instance But as fetching and matching from Map is slow , Is there other optimized way to do this ?
Found similar at this Question but dont feel that is optimized
