org.antlr.runtime.debug.Profiler
| Profiler | | public class Profiler extends BlankDebugEventListener (Code) | | Using the debug event interface, track what is happening in the parser
and record statistics about the runtime.

| Method Summary | |
| public void | LT(int i, Token t)
Track refs to lookahead if in a fixed/nonfixed decision. | | public void | beginBacktrack(int level)
Track backtracking decisions. | | public void | consumeHiddenToken(Token token)
| | public void | consumeToken(Token token)
| | protected static String[] | decodeReportData(String data)

| | public void | enterDecision(int decisionNumber)
| | public void | enterRule(String ruleName)
| | public void | examineRuleMemoization(IntStream input, int ruleIndex, String ruleName)
Track memoization; this is not part of standard debug interface
but is triggered by profiling. | | public void | exitDecision(int decisionNumber)
| | public void | exitRule(String ruleName)
| | public int | getNumberOfHiddenTokens(int i, int j)
| | public boolean | inDecision()
The parser is in a decision if the decision depth > 0. | | public void | memoize(IntStream input, int ruleIndex, int ruleStartIndex, String ruleName)

| RUNTIME_STATS_FILENAME | | final public static String RUNTIME_STATS_FILENAME(Code) | | |
| Version | | final public static String Version(Code) | | Because I may change the stats, I need to track that for later
computations to be consistent.

| Profiler | | public Profiler()(Code) | | |
| LT | | public void LT(int i, Token t)(Code) | | Track refs to lookahead if in a fixed/nonfixed decision.
|
| beginBacktrack | | public void beginBacktrack(int level)(Code) | | Track backtracking decisions. You'll see a fixed or cyclic decision
and then a backtrack.
enter rule
...
enter decision
LA and possibly consumes (for cyclic DFAs)
begin backtrack level
mark m
rewind m
end backtrack level, success
exit decision
...
exit rule
|
| consumeHiddenToken | | public void consumeHiddenToken(Token token)(Code) | | |
| consumeToken | | public void consumeToken(Token token)(Code) | | |
| endBacktrack | | public void endBacktrack(int level, boolean successful)(Code) | | Successful or not, track how much lookahead synpreds use
|
| enterDecision | | public void enterDecision(int decisionNumber)(Code) | | |
| examineRuleMemoization | | public void examineRuleMemoization(IntStream input, int ruleIndex, String ruleName)(Code) | | Track memoization; this is not part of standard debug interface
but is triggered by profiling. Code gen inserts an override
for this method in the recognizer, which triggers this method.
|
| exitDecision | | public void exitDecision(int decisionNumber)(Code) | | |
| getNumberOfHiddenTokens | | public int getNumberOfHiddenTokens(int i, int j)(Code) | | Get num hidden tokens between i..j inclusive
|
| inDecision | | public boolean inDecision()(Code) | | The parser is in a decision if the decision depth > 0. This
works for backtracking also, which can have nested decisions.
|
| semanticPredicate | | public void semanticPredicate(boolean result, String predicate)(Code) | | |
| terminate | | public void terminate()(Code) | | |
| trim | | protected int[] trim(int[] X, int n)(Code) | | |
