Class SolutionParserFactory

java.lang.Object
  parser.SolutionParserFactory

All Implemented Interfaces:

ParserFactory

public class SolutionParserFactory
extends java.lang.Object
implements ParserFactory

This class works as an interface for the parsing with the solution AST.

Constructor Summary

SolutionParserFactory()

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.
treeNodesSolution.Program	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

public void setLexer(CoolTokenLexer lexer)

Description copied from interface: ParserFactory

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

Specified by:

setLexer in interface ParserFactory

Parameters:

lexer - -- input to parser

parse

public void parse()
           throws java.lang.Exception

Description copied from interface: ParserFactory

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

Specified by:

parse in interface ParserFactory

Throws:

errorsDuringParse

public boolean errorsDuringParse()

Description copied from interface: ParserFactory

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

Specified by:

errorsDuringParse in interface ParserFactory
