Class ExposedTypeProcessor

java.lang.Object

org.python.expose.generate.ExposedTypeProcessor

All Implemented Interfaces:

org.objectweb.asm.Opcodes, PyTypes

public class ExposedTypeProcessor
extends java.lang.Object
implements org.objectweb.asm.Opcodes, PyTypes

Processes the bytecode of a Java class that has the ExposedType annotation on it and generates new bytecode for it containing the inner classes Jython needs to expose it as a type.
