CharacterRunAutomaton

class CharacterRunAutomaton(a: Automaton) : RunAutomaton

Automaton representation for matching char[].

Constructors

CharacterRunAutomaton

constructor(a: Automaton)

Properties

val accept: FixedBitSet

val alphabetSize: Int

val automaton: Automaton

val charIntervals: IntArray?

open val childResources: MutableCollection<Accountable>

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).

val classmap: IntArray

val points: IntArray

Returns number of states in automaton.

val transitions: IntArray

Functions

open operator override fun equals(obj: Any?): Boolean

fun getCharClass(c: Int): Int

Gets character class of given codepoint

open override fun hashCode(): Int

fun isAccept(state: Int): Boolean

Returns acceptance status for given state.

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.

fun run(s: String): Boolean

Returns true if the given string is accepted by this automaton.

fun run(s: CharArray, offset: Int, length: Int): Boolean

Returns true if the given char array is accepted by this automaton.

fun step(state: Int, c: 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.)

open override fun toString(): String

Returns a string representation of this automaton.
