| ClassWriter | | public class ClassWriter implements ClassVisitor(Code) | | A
ClassVisitor ClassVisitor that generates Java class files. More
precisely this visitor generates a byte array conforming to the Java class
file format. It can be used alone, to generate a Java class "from scratch",
or with one or more
ClassReader ClassReader and adapter class
visitor to generate a modified class from one or more existing Java classes.
