`static java.lang.String`	`getCommonSuffix(Automaton a)`	Returns the longest string that is a suffix of all accepted strings and visits each state at most once.
`static BytesRef`	`getCommonSuffixBytesRef(Automaton a)`
`static java.util.Set<IntsRef>`	`getFiniteStrings(Automaton a, int limit)`	Returns the set of accepted strings, assuming that at most `limit` strings are accepted.
`static boolean`	`isFinite(Automaton a)`	Returns true if the language of this automaton is finite.
`static java.util.Set<State>`	`reverse(Automaton a)`	Reverses the language of the given (non-singleton) automaton while returning the set of new initial states.

- Method Detail
  - isFinite
```
public static boolean isFinite(Automaton a)
```
    Returns true if the language of this automaton is finite.
  - getCommonPrefix
```
public static java.lang.String getCommonPrefix(Automaton a)
```
    Returns the longest string that is a prefix of all accepted strings and visits each state at most once.
    
    Returns:
    
    common prefix
  - getCommonPrefixBytesRef
```
public static BytesRef getCommonPrefixBytesRef(Automaton a)
```
  - getCommonSuffix
```
public static java.lang.String getCommonSuffix(Automaton a)
```
    Returns the longest string that is a suffix of all accepted strings and visits each state at most once.
    
    Returns:
    
    common suffix
  - getCommonSuffixBytesRef
```
public static BytesRef getCommonSuffixBytesRef(Automaton a)
```
  - reverse
```
public static java.util.Set<State> reverse(Automaton a)
```
    Reverses the language of the given (non-singleton) automaton while returning the set of new initial states.
  - getFiniteStrings
```
public static java.util.Set<IntsRef> getFiniteStrings(Automaton a,
                                                      int limit)
```
    Returns the set of accepted strings, assuming that at most limit strings are accepted. If more than limit strings are accepted, the first limit strings found are returned. If limit<0, then the limit is infinite.
