## Class AbstractBitwiseTrie<K,V>

- java.lang.Object
- - java.util.AbstractMap<K,V>
  - - org.apache.commons.collections4.trie.AbstractBitwiseTrie<K,V>

- Type Parameters:
    `K` - the type of the keys in this map
    `V` - the type of the values in this map
  All Implemented Interfaces:
    Serializable, Map<K,V>, SortedMap<K,V>, Get<K,V>, IterableGet<K,V>, IterableMap<K,V>, IterableSortedMap<K,V>, OrderedMap<K,V>, Put<K,V>, Trie<K,V>
  Direct Known Subclasses:
    PatriciaTrie

      public abstract class AbstractBitwiseTrie<K,V>
      extends AbstractMap<K,V>
      implements Trie<K,V>, Serializable

  This class provides some basic `Trie` functionality and utility methods for actual bitwise `Trie` implementations.
