Class AbstractTrie<V>

  • Type Parameters:
    V - the type of object that the Trie holds
    All Implemented Interfaces:
    Trie<V>
    Direct Known Subclasses:
    ArrayTernaryTrie, ArrayTrie, TreeTrie
    public abstract class AbstractTrie<V>
extends java.lang.Object
implements Trie<V>
    Abstract Trie implementation.

    Provides some common implementations, which may not be the most efficient. For byte operations, the assumption is made that the charset is ISO-8859-1
