Sam Harwell aeb43069aa Move reach variable inside loop. Remove unnecessary ATNConfigSet clone. 2012-03-13 19:25:39 -05:00
Sam Harwell 51a15ac4a7 ATNConfigSet prior to error is closure, not reach. Reach is empty. 2012-03-13 19:25:38 -05:00

Sam Harwell dce72dcbfb * 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)

Sam Harwell bbff5bd20a New tests related to if/if/else constructs 2012-03-12 07:26:39 -05:00
Sam Harwell 50180825d9 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
Sam Harwell 04cd48e88d No need to fully evaluate predicates when called from execDFA because ambiguous alts aren't reported anyway. 2012-03-10 16:32:10 -06:00
Sam Harwell 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. 2012-03-10 16:16:39 -06:00

Sam Harwell 5deab167a1 ParseTreeVisitor.visit takes a ParseTree... only visitChildren takes a RuleNode 2012-03-04 12:52:43 -06:00

Terence Parr 2ba5a1f12a Made the parse tree visitor walk ParseTree objects not ParserRuleContext objects. This necessitated pulling up the accept() and toStringTree(Parser) methods into ParseTree. 2012-03-01 17:57:49 -08:00
