API request exists(Fqn, key)

[mfrost]

Would it be possible to include the following on TreeCache:

boolean exists(Fqn fqn, String key)

Which will return true if a value exists at the specified node for the specified key.

I've currently used the get(Fqn, key) method and tested for null.

cheers

I recently added an exists(Fqn) method, I'll add another one for exists(Fqn, Object key).

Note, that there is a diff between get() and exists(): get will try to load the node/value from the CacheLoader, whereas exists() will not (just a memory check).
