Class OutputFile

java.lang.Object

org.javacc.parser.OutputFile

public class OutputFile
extends Object

This class handles the creation and maintenance of the boiler-plate classes, such as Token.java, JavaCharStream.java etc. It is responsible for:

• Writing the JavaCC header lines to the file.
• Writing the checksum line.
• Using the checksum to determine if an existing file has been changed by the user (and so should be left alone).
• Checking any existing file's version (if the file can not be overwritten).
• Checking any existing file's creation options (if the file can not be overwritten).
