java.lang.Object
- org.apache.lucene.util.graph.GraphTokenStreamFiniteStrings

```
public final class GraphTokenStreamFiniteStrings
extends Object
```
Consumes a TokenStream and creates an Automaton where the transition labels are terms from the TermToBytesRefAttribute. This class also provides helpers to explore the different paths of the Automaton.
