Method Summary

Modifier and Type	Method and Description
(package private) void	add(Node root)
(package private) void	addConstant(java.lang.String newcode) Constants (true, false, null) are considered basically free, because it's likely that they will get folded when we're done.
(package private) void	addIdentifier(java.lang.String identifier)
(package private) void	append(java.lang.String str) Appends a string to the code, keeping track of the current line length.
(package private) boolean	continueProcessing() Provides a means of interrupting the CodeGenerator.
(package private) int	getCost()
(package private) char	getLastChar() Retrieve the last character of the last string sent to append.

Method Detail

add

void add(Node root)

getCost

int getCost()

continueProcessing

boolean continueProcessing()

Description copied from class: CodeConsumer

Provides a means of interrupting the CodeGenerator. Derived classes should return false to stop further processing.

Overrides:

continueProcessing in class CodeConsumer

getLastChar

char getLastChar()

Description copied from class: CodeConsumer

Retrieve the last character of the last string sent to append.

Specified by:

getLastChar in class CodeConsumer

append

void append(java.lang.String str)

Description copied from class: CodeConsumer

Appends a string to the code, keeping track of the current line length. NOTE: the string must be a complete token--partial strings or partial regexes will run the risk of being split across lines. Do not directly append newlines with this method. Instead use CodeConsumer.startNewLine().

Specified by:

append in class CodeConsumer

addIdentifier

void addIdentifier(java.lang.String identifier)

Overrides:

addIdentifier in class CodeConsumer

addConstant

void addConstant(java.lang.String newcode)

Constants (true, false, null) are considered basically free, because it's likely that they will get folded when we're done.

Overrides:

addConstant in class CodeConsumer
