[jboss-user] [JBossCache] - Node locking question
Hi. I'm kicking the tires on integrating JBossCache (2.0beta) into an app of mine.
So far looks pretty good, but I've run into one small snag.
I would like to find a way to atomically replace the contents of a node - i.e., perform:
node.clearData()
followed by
node.putAll(map)
all while the node is being locked.
In other words, a method something like:
node.setData(map)
if it existed.
From what I can glean from the (somewhat minimal) details in the docs
about locking, it looks like the putAll method operates under a lock, which is somewhat
helpful. But the problem with using that is that if the old map contained mappings that
don't exist in the new one, the old mappings will still remain in the node's data.
So what I'm looking for is a way to replace the node's entire data. Any
thread-safe way to do that?
TIA,
DR
