Predicate<K>

public interface KeyFilter<K>
extends Predicate<K>
```
Deprecated.
since 9.3 This will be replaced by Predicate in the future

A filter for keys. This class is complemented by the KeyValueFilter class. This class is useful for cases when it may be more beneficial to not have the values available. This would include cache loaders since many implementations it may incur additional performance costs just to resurrect the values in addition to any keys.
