public class MapFilter<K,V>
extends KorypheFunction<Map<K,V>,Map<K,V>>

A MapFilter is a Function that filters items from a Map based on a Predicate. You can provide a key predicate, value predicate and keyValuePredicate. All predicates must return true for the entry to be valid and kept. If a predicate is not provided then it will default to returning true.
