serp.bytecode.lowlevel.ClassEntry

All Implemented Interfaces:

ConstantEntry, VisitAcceptor

public class ClassEntry
extends Entry
implements ConstantEntry

A constant pool entry describing a class. Class entries are used to refer to the current class, the superclass, implemented interfaces, etc. Each class entry contains the constant pool index of the UTF8Entry that stores the class name, which is represented in internal form.
