This package contains classes which are wrappers for opcode instructions contained
in the code field of a Code attribute structure. These classes are not
generated when reading the org.gjt.jclasslib.structures.ClassFile structure via
the org.gjt.jclasslib.io.ClassFileReader, they have to be created through the
org.gjt.jclasslib.io.ByteCodeReader and converted back to bytecode with the
org.gjt.jclasslib.io.ByteCodeWriter.
