Member Function Documentation
| virtual RefAST TreeParser::getAST | ( | ) | [pure virtual] |
Get the AST return value squirreled away in the parser.
Make sure current lookahead symbol matches the given set Throw an exception upon mismatch, which is caught by either the error handler or by a syntactic predicate.

| 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.

Field Documentation
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.
Definition at line 96 of file TreeParser.hpp.
ASTFactory* TreeParser::astFactory [protected] |
AST support code; parser and treeparser delegate to this object
Definition at line 114 of file TreeParser.hpp.
TreeParserSharedInputState TreeParser::inputState [protected] |
int TreeParser::traceDepth [protected] |
Used to keep track of indent depth with -traceTreeParser
