public class emit extends Object
Three classes are produced by this code:
Three parse tables are created as part of the parser class:
In addition to the method interface, this class maintains a series of public global variables and flags indicating how misc. parts of the code and other output is to be produced, and counting things such as number of conflicts detected (see the source code and public variables below for more details).
This class is "static" (contains only static data and methods).
