<p>Traverses a UChar-serialized data structure with minimal state, for mapping strings (16-bit-unit sequences) to non-negative integer values.</p>
<p>This class owns the serialized trie data only if it was constructed by the builder's build() method. The public constructor and the copy constructor only alias the data (only copy the pointer). There is no assignment operator.</p>
