Class BoolConst

java.lang.Object
  BoolConst

class BoolConst

extends java.lang.Object

This clas encapsulates all aspects of code generation for boolean constatns. String constants and Int constants are handled by StringTable and IntTable respectively, but since there are only two boolean constants, we handle them here.

Field Summary

(package private) static BoolConst	falsebool
(package private) static BoolConst	truebool
private boolean	val

Constructor Summary

(package private)	BoolConst(boolean val) Creates a new boolean constant.
(package private)	BoolConst(java.lang.Boolean val) Creates a new boolean constant.

Method Summary

void	codeDef(int boolclasstag, java.io.PrintStream s) Generates code for the boolean constant definition.
void	codeRef(java.io.PrintStream s) Emits a reference to this boolean constant.

Constructor Detail

BoolConst

BoolConst(boolean val)

Creates a new boolean constant.

Parameters:

val - the value

BoolConst

BoolConst(java.lang.Boolean val)

Creates a new boolean constant.

Parameters:

val - the value

Method Detail

codeRef

public void codeRef(java.io.PrintStream s)

Emits a reference to this boolean constant.

Parameters:

s - the output stream

codeDef

public void codeDef(int boolclasstag,
                    java.io.PrintStream s)

Generates code for the boolean constant definition. This method is incomplete; you get to finish it up in programming assignment 5.

Parameters:

boolclasstag - the class tag for string object

s - the output stream
