org.eclipse.persistence.internal.libraries.asm.ClassWriter
A {@link ClassVisitor ClassVisitor} that generates Java class files. Moreprecisely 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 {@link ClassReader ClassReader} and adapter classvisitor to generate a modified class from one or more existing Java classes. @author Eric Bruneton
