grammar |
|
protected Set<State> |
markedStates |
To prevent infinite recursion when walking state machines, record
which states we've visited.
|
protected int |
stateCounter |
Each state we walk will get a new state number for serialization
purposes.
|
protected Map<State,Integer> |
stateNumberTranslator |
Rather than add a new instance variable to NFA and DFA just for
serializing machines, map old state numbers to new state numbers
by a State object → Integer new state number HashMap.
