Class Skeleton

java.lang.Object

jflex.skeleton.Skeleton

public class Skeleton
extends Object

This class stores the skeleton of generated scanners.

The skeleton consists of several parts that can be emitted to a file. Usually there is a portion of generated code (produced in class Emitter) between every two parts of skeleton code.

There is a static part (the skeleton code) and state based iterator part to this class. The iterator part is used to emit consecutive skeleton sections to some PrintWriter.

Version:

JFlex 1.9.1
