Sam Harwell 3f1f76df7d 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.

Sam Harwell 768bfc0cf2 Add ProxyErrorListener to allow dispatching error reporting to multiple listeners without manually iterating over the list of listeners. 2012-03-12 15:07:48 -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
Sam Harwell b570641e2b Simplify ParseTree.visitChildren; ParseTree.visit and visitChildren take a RuleNode parameter; update comments 2012-03-04 12:17:43 -06:00
Sam Harwell a948736729 TerminalNodeImpl.isErrorNode now tests for ErrorNode interface instead of ErrorNodeImpl implementation 2012-03-03 21:57:49 -06:00

Terence Parr 0375f8318a rename a parameter 2012-03-01 18:01:27 -08:00
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

Terence Parr 600c4bbd91 crap. sun already made IdentityHashMap; rm'ing my version 2012-02-25 16:07:34 -08:00
Terence Parr 73ae2b0bfc Added ParseTreeProperty and added generically useful Map that ignores key.hashCode and equals() and simply uses key identity instead. In particular, this is useful for ANTLR because parse trees are actually interfaces laid on top of the rule context objects used by ANTLR's grammar analysis. These context objects use special equals methods and so on. Plus, when we want to annotate trees with values, we want a specific note to have a value. Identity is what we intend. 2012-02-25 13:43:32 -08:00
