| Improve this Doc View SourceGetCommonPrefix(Automaton)
Returns the longest string that is a prefix of all accepted strings and visits each state at most once.
Declaration
public static string GetCommonPrefix(Automaton a)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a |
Returns
| Type | Description |
|---|---|
| System.String | Common prefix. |

Declaration
public static BytesRef GetCommonPrefixBytesRef(Automaton a)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a |
Returns
| Type | Description |

| BytesRef |
GetCommonSuffix(Automaton)
Returns the longest string that is a suffix of all accepted strings and visits each state at most once.
Declaration

GetCommonSuffixBytesRef(Automaton)
Declaration
public static BytesRef GetCommonSuffixBytesRef(Automaton a)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a |
Returns
| Type | Description |
|---|---|
| BytesRef |
GetFiniteStrings(Automaton, Int32)
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.
Declaration
public static ISet<Int32sRef> GetFiniteStrings(Automaton a, int limit)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a | |
| System.Int32 | limit |
Returns
| Type | Description |
|---|---|
| System.Collections.Generic.ISet<Int32sRef> |
IsFinite(Automaton)
Returns true if the language of this automaton is finite.
Declaration
public static bool IsFinite(Automaton a)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a |
Returns
| Type | Description |
|---|---|
| System.Boolean |
Reverse(Automaton)
Reverses the language of the given (non-singleton) automaton while returning the set of new initial states.
Declaration
public static ISet<State> Reverse(Automaton a)Parameters
| Type | Name | Description |
|---|---|---|
| Automaton | a |
Returns
| Type | Description |
|---|---|
| System.Collections.Generic.ISet<State> |
