All Implemented Interfaces:

org.objectweb.asm.Opcodes, PyTypes

public class DescriptorExposer
extends Exposer

Generates a class to expose a descriptor on Python type. One of addMethodGetter or addFieldGetter must be called, and possibly one of addMethodSetter and addFieldSetter if this is a settable descriptor. If this is a deletable descriptor, addMethodDeleter may be called. There is no addFieldDeleter since there's no defined behavior to 'delete' a field.
