Constructor Detail

CharacterRunAutomaton

public CharacterRunAutomaton(Automaton a)

Construct with a default determinizeWorkLimit..

CharacterRunAutomaton

public CharacterRunAutomaton(Automaton a,
                             int determinizeWorkLimit)

Constructor specifying determinizeWorkLimit.

Parameters:

a - Automaton to match

determinizeWorkLimit - maximum effort to spend determinizing the automataon. If more effort is required then a TooComplexToDeterminizeException is thrown. Use Operations.DEFAULT_DETERMINIZE_WORK_LIMIT as a decent default if you don't otherwise know what to specify.
