             Summary: Extend KeyFilter facility to the whole cache
                 Key: ISPN-3640
                 URL: https://issues.jboss.org/browse/ISPN-3640
             Project: Infinispan
          Issue Type: Feature Request
          Components: Core API
    Affects Versions: 6.0.0.CR1
            Reporter: Paul Ferraro
            Assignee: Mircea Markus


The key filter facility is very convenient for users who have multiple key types in the same cache.  It would be very handy if this feature were extended to the whole cache.
e.g.

Cache<?, ?> cache = ...;
KeyFilter filter = ...;
Cache<K, V> view = cache.filter(filter);
view.addListener(listener) // Equivalent to the current cache.addListener(listener, filter) method
for (Map.Entry<K, V> entry: view.entrySet()) {
   ...
}
