A fast and thorough lazy object proxy.

* Free software: BSD 2-Clause License

Note that this is based on `wrapt`_'s ObjectProxy with one big change: it calls a function the first time the proxy object is
used, while `wrapt.ObjectProxy` just forwards the method calls to the target object.

In other words, you use `lazy-object-proxy` when you only have the object way later and you use `wrapt.ObjectProxy` when you
want to override few methods (by subclassing) and forward everything else to the target object.

Example::

    import lazy_object_proxy

    def expensive_func():
        from time import sleep
        print('starting calculation')
        # just as example for a very slow computation
        sleep(2)
        print('finished calculation')
        # return the result of the calculation
        return 10

    obj = lazy_object_proxy.Proxy(expensive_func)
    # function is called only when object is actually used
    print(obj)  # now expensive_func is called

    print(obj)  # the result without calling the expensive_func

Installation
============

::

    pip install lazy-object-proxy

You can also install the in-development version with::

    pip install https://github.com/ionelmc/python-lazy-object-proxy/archive/master.zip


Documentation
=============


https://python-lazy-object-proxy.readthedocs.io/


Development
===========

To run all the tests run::

    tox

Acknowledgements
================

This project is based on some code from `wrapt`_ as you can see in the git history.
