[jbosscache-dev] Some new Cache usage questions

[Ben Wang]

Thing is I only do put to specific fqn once. So caching it doesn't buy you anything.

My 2 cents: I'd rather keep the API clean, at the expense of folks potentially writing wrapping code (like Ben).

Your code samples look a bit weird:
#1
Why do you always get the child ? Can't you get the node and cache it, e.g.
Node n=cache.getRoot().getChild(fqn);
n.containsKey(PojoInstance.KEY)

#2
Same as for #1: you don't need to call cache.getRoot().getChild(fqn) all the time, for example in a loop, simply cache it
