public interface ParserFactory

Method Summary

void	debug_parse()
boolean	errorsDuringParse() After parsing, the return value of this method will be valid.
java.lang.String	getDumpedAST() Returns the AST from the parse as dumped into a string.
java.lang.Object	getResultAST()
void	parse() After setting the lexer, this parse() is the command to parse the stream coming from the lexer, debug_parse() does so in debug mode.
void	semant() Runs the semantic checker on the AST accessible by getResultAST().
void	setLexer(CoolTokenLexer lexer) This method is used to specify the input to the parser.

Method Detail

setLexer

void setLexer(CoolTokenLexer lexer)

This method is used to specify the input to the parser.

Parameters:

lexer - -- input to parser

parse

void parse()
           throws java.lang.Exception

After setting the lexer, this parse() is the command to parse the stream coming from the lexer, debug_parse() does so in debug mode.

Throws:

java.lang.Exception - -- if unrecoverable exception occured during parsing.

debug_parse

void debug_parse()
                 throws java.lang.Exception

Throws:

java.lang.Exception

errorsDuringParse

boolean errorsDuringParse()

After parsing, the return value of this method will be valid.

getResultAST

java.lang.Object getResultAST()

semant

void semant()
            throws java.lang.Exception

Runs the semantic checker on the AST accessible by getResultAST().

Throws:

java.lang.Exception - -- if there are exceptions during semantic checking.

getDumpedAST

java.lang.String getDumpedAST()

Returns the AST from the parse as dumped into a string.
