LexerATNSimulator.accept(CharStream input,
LexerActionExecutor lexerActionExecutor,

protected void |
LexerATNSimulator.captureSimState(LexerATNSimulator.SimState settings,

DFAState dfaState) |
protected boolean |
LexerATNSimulator.closure(CharStream input,
LexerATNConfig config,
ATNConfigSet configs,
boolean currentAltReachedAcceptState,
boolean speculative,
boolean treatEofAsEpsilon)
Since the alternatives within any lexer decision are ordered by
preference, this method stops pursuing the closure as soon as an accept
state is reached.
|
protected ATNConfigSet |
LexerATNSimulator.computeStartState(CharStream input,
ATNState p) |
protected DFAState |
LexerATNSimulator.computeTargetState(CharStream input,
DFAState s,
int t)
Compute a target state for an edge in the DFA, and attempt to add the
computed state and corresponding edge to the DFA.
|
void |
LexerATNSimulator.consume(CharStream input) |
protected boolean |
LexerATNSimulator.evaluatePredicate(CharStream input,
int ruleIndex,
int predIndex,
boolean speculative)
Evaluate a predicate specified in the lexer.
|
protected int |
LexerATNSimulator.execATN(CharStream input,
DFAState ds0) |
void |
LexerActionExecutor.execute(Lexer lexer,
CharStream input,
int startIndex)
Execute the actions encapsulated by this executor within the context of a
particular
Lexer . |
protected int |

Given a starting configuration set, figure out all ATN configurations
we can reach upon input
t . |
