Enclosing class:

ClassWriter

public abstract static class ClassWriter.Element
extends java.lang.Object

An Element is an object that can be serialized into a byte buffer. Serialization via 'copyInto' is performed when the user calls makeBytes() on the ClassWriter. At this time no new constant pool items can be allocated, so any item indices that need to be emitted must be allocated earlier.
