Member Function Documentation

virtual RefAST TreeParser::getAST (    )  [pure virtual]

Get the AST return value squirreled away in the parser.

virtual ASTFactory* TreeParser::getASTFactory (    )  const [inline, virtual]

Return pointer to ASTFactory.

virtual int TreeParser::getNumTokens (    )  [pure virtual]

Return the number of tokens defined.

virtual const char* TreeParser::getTokenName (  int    num )  const [pure virtual]

Get the name for token 'num'.

virtual const char* const* TreeParser::getTokenNames (    )  [pure virtual]

Return an array of getNumTokens() token names.

void TreeParser::match (  RefAST    t, int    ttype )  [protected, virtual]

void TreeParser::match (  RefAST    t, const BitSet &    b )  [virtual]

Make sure current lookahead symbol matches the given set Throw an exception upon mismatch, which is catch by either the error handler or by the syntactic predicate.

void TreeParser::matchNot (  RefAST    t, int    ttype )  [protected, virtual]

void TreeParser::panic (    )  [virtual]

Give panic message and exit the program. can be overridden in subclass Deprecated: this method is unused and will dissappear in the next release

void TreeParser::reportError (  const ANTLR_USE_NAMESPACE(std) string &    s )  [virtual]

Parser error-reporting function can be overridden in subclass. Parser error-reporting function can be overridden in subclass

void TreeParser::reportError (  const RecognitionException &    ex )  [virtual]

Parser error-reporting function can be overridden in subclass. Parser error-reporting function can be overridden in subclass

void TreeParser::reportWarning (  const ANTLR_USE_NAMESPACE(std) string &    s )  [virtual]

Parser warning-reporting function can be overridden in subclass. Parser warning-reporting function can be overridden in subclass

virtual void TreeParser::setASTFactory (  ASTFactory *    factory )  [inline, virtual]

Specify the AST factory to be used during tree building. (Compulsory) Setting the factory is compulsory (if you intend to modify the tree in the treeparser). The AST Factory is shared between parser (who builds the initial AST) and treeparser. See also: Parser::getASTFactory()

void TreeParser::traceIn (  const char *    rname, RefAST    t )  [virtual]

void TreeParser::traceIndent (    )  [virtual]

These are used during when traceTreeParser commandline option is passed. Procedure to write out an indent for traceIn and traceOut

void TreeParser::traceOut (  const char *    rname, RefAST    t )  [virtual]

Member Data Documentation

ASTFactory* TreeParser::astFactory [protected]

AST support code; parser and treeparser delegate to this object

RefAST TreeParser::ASTNULL [static]

The AST Null object; the parsing cursor is set to this when it is found to be null. This way, we can test the token type of a node without having to have tests for 0 everywhere.

TreeParserSharedInputState TreeParser::inputState [protected]

The input state of this tree parser.

int TreeParser::traceDepth [protected]

Used to keep track of indent depth with -traceTreeParser
