Class SectHeadScanner

java.lang.Object
  net.sourceforge.czt.print.z.SectHeadScanner

All Implemented Interfaces:

net.sourceforge.czt.java_cup.runtime.Scanner

public class SectHeadScanner
extends java.lang.Object
implements net.sourceforge.czt.java_cup.runtime.Scanner

This is a scanner that creates SECTHEAD tokens of type ZSect for section headers. In most cases, it just forwards the stream of tokens unchanged via the #next_token method. When it encounters a ZED token followed by a SECTION token (the beginning of a section header), it parses untill the end of the section header definition and returns a SECTHEAD token whos type is a ZSect containing all the parsed information. If no section header definition can be found, one is included before the first non-text token. Parser using this scanner do not need to care about anonymous specifications.
