proguard.classfile
Class ProgramClassFile

java.lang.Object
  proguard.classfile.ProgramClassFile

All Implemented Interfaces:: ClassFile, VisitorAccepter

public class ProgramClassFile
extends Object
implements ClassFile

This is a complete representation of the data in a Java class file. A ClassFile instance can be generated using the static create(DataInput) method, manipulated using various operators, and persisted back using the write(DataOutput) method.
