Constructor Detail

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 automataon can have once determinized. If more states are required to determinize it then a TooComplexToDeterminizeException is thrown.
