In order to have monitor function for the application's admin page,
I would like to have Cache class with admin functions, such as list up all the cached objects, and get size of cached objects.

I am thinking to add following codes locally now, but I could not find the method only for valid cached onjects. I could filter only valid objects manually, so it would be all right.
I would really appreciate it, if you would consider my proposal in future release.

Here is the code.
---- Cache.java ----
public int size()
{
  return cacheMap.size();
}

public Set keySet()
{
  return cacheMap.keySet();
}
