ObjectProxy

A minimalistic yet powerful object proxying utility

This readme attempts to explain the general use of this library.

Installation

• Install from repository

pip install git+https://github.com/aviksama/objectproxy.git

• Install from pypi

pip install object-proxy

Example

Object proxy basically creates a proxy for any python object:

class MyClass(object):

    def __init__(self, array=None):
        self.array = array or []

    def get_array_element(self, index):
        try:
            return self.array[index]
        except IndexError:
            return


def create_dictionary_of_objects(*args):
    mydict = dict()
    for index, arg in enumerate(args):
        mydict[index] = arg
    return mydict

Now lets create proxies for the objects above in random fashion

>>> from objectproxy import ProxyElement, eval_proxy

>>> class_proxy = ProxyElement(MyClass, args=[[1,2,3],], kwargs={})
>>> function_proxy = ProxyElement(create_dictionary_of_objects, args=[class_proxy], kwargs={})
>>> class_proxy_ref = function_proxy[0]
>>> class_proxy_array_element = class_proxy_ref.get_array_element(0)
>>> eval_proxy(class_proxy_array_element)
1

until eval_proxy is called on the proxy object, It doesn't call the parent methods. Hence all the parent methods and attributes are lazily evaluated.
