Ensure that serialized transitions only point to states which weren't removed. Add unit test for a current failure case (will be a regression test once fixed).

Move reportAmbiguity, reportContextSensitivity, reportAttemptingFullContext, reportInsufficientPredicates from ANTLRErrorStrategy to ANTLRErrorListener.
...
Add BaseErrorListener to allow implementing ANTLRErrorListener without implementing every method (e.g. ConsoleErrorListener).
DiagnosticErrorStrategy is now DiagnosticErrorListener, updated tests.

* Recognizer._listeners initialized to have a single ConsoleErrorListener
...
* Use CopyOnWriteArrayList so listeners can be added/removed in callbacks
* Remove special handling for _listeners null or empty (never null, ConsoleErrorListener will be present if feature is desired)

Add boolean field ParserATNSimulator.reportAmbiguities (default true). When false, ambiguous alts aren't reported which allows usage of (the faster) incomplete semantic predicate evaluation even within execATN.
2012-03-10 16:41:57 -06:00

No need to fully evaluate predicates when called from execDFA because ambiguous alts aren't reported anyway.

2cc39c2f9b
Evaluate predicates for all ambiguous alternatives and report if still ambiguous after predicate evaluation. Remove misleading message insufficient predicates. Fixes antlr/antlr4#31 . Partially addresses antlr/antlr4#39 .
