[jbosscache-dev] RegionManager

[Ben Wang]

Regarding Cache.getRegion(fqn) API, I also need to have an API that do like Cache.findRegion(fqn) that returns null if absent. So I am thinking either:

1. Create a new api, findRegion(fqn), or
2. modify the getRegion(fqn) to getRegion(fqn, createIfAbsent)

What one do you prefer?

Currently it will create another new region under the children fqn.

Sounds very logical. What does it do now?
