Design Question...

[Daniel Pereira]

I'm not planning on sending my solution to Sun like this, but if I synchronize a singleton data object like so:

synchronized (myData) {

switch(request.getAction()){
CASE SEARCH:
myData.search_method...
break;
CASE UPDATE:
myData.update_method...
break;
}

}

Wouldn't locking and unlocking individual records be redundant? Would I fail if I implemented the lock methods and called them even though concurrent threads would never be able to access the same record because they'd have to queue up through a synchronized bottleneck switch? Opinions? Is there a race condition scenario I'm not thinking about? I understand that I *must* implement locking the way described in the interface, but for a low-volume application this design seems like an arguable solution.
