Guys,

I have a situation where I need to retrive all the keys in my
KeyedCache - however, KeyedCache extends LRU, which it turn uses
apache commons LRUMap internally.

The LRU class has a private val map: LRUMap

Is there any objections to me adding a method to LRU to return all the
keys from that map?:

// off the top of my head...
def keys: Array[KeyType] = map.keySet().asInstanceOf[Set
[KeyType]].toArray

Thoughts?

Cheers, Tim
