访问Python类的函数子集

我不能100%确定这是否是您想要的,但它是有效的:

def proxy_wrapper(name, docstring):
    def wrapper(self, *args, **kwargs):
        return self.proxy.__getattribute__(name)(*args, **kwargs)
    wrapper.__doc__ = docstring
    wrapper._is_wrapper = True
    return wrapper

class Something(object):
    def __init__(self):
        self.proxy = {}

    @classmethod
    def get_proxy_wrappers(cls):
        return [m for m in dir(cls) if hasattr(getattr(cls, m), "_is_wrapper")]

    update = proxy_wrapper("update", "wraps the proxy's update() method")
    proxy_keys = proxy_wrapper("keys", "wraps the proxy's keys() method")    

>>> a = Something()
>>> print a.proxy
{}
>>> a.update({1: 42})
>>> print a.proxy
{1: 42}
>>> a.update({"foo": "bar"})
>>> print a.proxy_keys()
[1, 'foo']
>>> print a.get_proxy_wrappers()
['proxy_keys', 'update']

使用xml rpc内省获取服务器列表,并将其与对象的属性相交。比如:

loc = dir(self)
rem = proxy.listMethods() # However introspection gets a method list
wrapped = [x for x in rem if x in loc]
