Constructor Details

CharacterRunAutomaton

public CharacterRunAutomaton(Automaton a)

Construct with a default number of maxDeterminizedStates.

CharacterRunAutomaton

public CharacterRunAutomaton(Automaton a,
 int maxDeterminizedStates)

Construct specifying maxDeterminizedStates.

Parameters:

a - Automaton to match

maxDeterminizedStates - maximum number of states that the automaton can have once determinized. If more states are required to determinize it then a TooComplexToDeterminizeException is thrown.

Method Details

run

public boolean run(String s)

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

run

public boolean run(char[] s,
 int offset,
 int length)

Returns true if the given string is accepted by this automaton
