Constructors

RunAutomaton(Automaton, int, bool)

Constructs a new RunAutomaton from a deterministic Automaton.

Declaration
protected RunAutomaton(Automaton a, int maxInterval, bool tableize)
Parameters
Type Name Description
Automaton a

An automaton.
int maxInterval
bool tableize

Fields

m_accept

Finite-state automaton with fast run operation.

Note

This API is experimental and might change in incompatible ways in the next release.

Declaration
protected readonly bool[] m_accept
Field Value
Type Description
bool[]

m_initial

Finite-state automaton with fast run operation.

Note

This API is experimental and might change in incompatible ways in the next release.

Declaration
protected readonly int m_initial
Field Value
Type Description
int

m_transitions

Finite-state automaton with fast run operation.

Note

This API is experimental and might change in incompatible ways in the next release.

Declaration
protected readonly int[] m_transitions
Field Value
Type Description
int[]

Properties

Count

Returns number of states in automaton.

NOTE: This was size() in Lucene.
Declaration
public int Count { get; }
Property Value
Type Description
int

InitialState

Returns initial state.

Declaration
public int InitialState { get; }
Property Value
Type Description
int

Methods

Equals(object)

Determines whether the specified object is equal to the current object.

Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
object obj

The object to compare with the current object.
Returns
Type Description
bool

true if the specified object is equal to the current object; otherwise, false.
Overrides

GetCharIntervals()

Returns array of codepoint class interval start points. The array should not be modified by the caller.

Declaration
public int[] GetCharIntervals()
Returns
Type Description
int[]

GetHashCode()

Serves as the default hash function.

Declaration
public override int GetHashCode()
Returns
Type Description
int

A hash code for the current object.
Overrides

IsAccept(int)

Returns acceptance status for given state.

Declaration
public bool IsAccept(int state)
Parameters
Type Name Description
int state
Returns
Type Description
bool

Step(int, int)

Returns the state obtained by reading the given char from the given state. Returns -1 if not obtaining any such state. (If the original Automaton had no dead states, -1 is returned here if and only if a dead state is entered in an equivalent automaton with a total transition function.)

Declaration
public int Step(int state, int c)
Parameters
Type Name Description
int state
int c
Returns
Type Description
int

ToString()

Returns a string representation of this automaton.

Declaration
public override string ToString()
Returns
Type Description
string
