Friends class   ParserException Detailed Description Scene Description Language Parser. The Parser class encapsulates the syntactial and semantical analysis of a scene description language (SDL) program, also known as Scene. It parses the Scene and generates code for a virtual machine which than produces the scene graph needed for the raytracing algorithm. Constructor & Destructor Documentation Parser::Parser ( Scanner & rScanner, OutputStream & error_stream )   Create a new instance of the parser. Parameters: rScanner   Reference to a Scanner performing the lexical analysis. error_stream   OutputStream used to report error messages. Member Function Documentation ObjectFile * Parser::getProgram ( )   Get the resulting compiled scene program, needed as input for the virtual machine. See also: VirtualMachine bool Parser::parse ( )   Parses the Scene Program. Returns: true if scene was a valid scene file, false if errors occured bool Parser::parseCompoundStatement ( BlockAction & action ) [protected]   Parses a Compound Statement (blocks of curly brackets). A Compound Statement is the basic building block for object initialization and functions, loops, if's and other commands. Therefore the concrete actions performed in a compound statement rely on the context where it is used. Therefore a "action" object is used to perform this context depended actions. If it is just used a statement group (e.g. if or loops), no special actions are to be performed. Therefore there exists a NullBlockAction which does nothing. (BNF) TODO Parameters: in, out   ] action the action class used to perform special operations in the compound statement bool Parser::parseInstanciation ( Class *& rpClass, SPToken & rErrorToken ) [protected]   Parses the Instanciation of Objects in the Scene Description Language. (BNF) instanciation ::= identifier compound-statement Parameters: out   ] rpClass the class identified by the identifier out   ] rErrorToken a error token that should used if a semantical error occurs (it point to the identifier token - the object name) The object instance is the top element on the VM stack. The documentation for this class was generated from the following file: Parser.h
