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
Sam Harwell 90bcfec456 Simplify CodeGenerator 2012-02-24 15:58:21 -06:00

Sam Harwell 2c8ef6470f Despite being absurdly verbose in Java, use callable objects instead of reflection in CodeGenerator because the latter is prone to runtime errors and debugging headaches 2012-02-23 16:44:54 -06:00

Sam Harwell 7dcb148d73 CommonTokenStream now extends BufferedTokenStream<Token> instead of BufferedTokenStream<CommonToken>. Token interface provides the same information and the change helps the work on improving generics. 2012-02-23 16:13:11 -06:00
Sam Harwell d7dbef2782 Can get token start and stop index from Token interface now 2012-02-23 16:13:11 -06:00

Sam Harwell 7c0d5cd726 Fix use of v3 runtime generics 2012-02-22 15:44:17 -06:00
Terence Parr 8a34176d82 added listener unit tests. fixed bug that didn't create ctx getters properly for recursive rules. added Symbol extends Token to parse tree stuff. added visitTerminal to Visitor. recursive alts now track their original, unedited AltAST subtree so we can properly count rule refs etc... later. dup of RuleRefAST was making wrong node. don't gen dispatch methods if no listener. 2012-02-22 12:44:33 -08:00

Sam Harwell d166e6d5d1 Emit grammar file name instead of generated class file name in generated implementation of getGrammarFileName(). Implement getGrammarFileName() in generated parser. 2012-02-20 17:14:19 -06:00
