Metadata-Version: 1.0
Name: ExtensionClass
Version: 2.13.2
Summary: Metaclass for subclassable extension types
Home-page: http://pypi.python.org/pypi/ExtensionClass
Author: Zope Foundation and Contributors
Author-email: zope-dev@zope.org

Description: ExtensionClass and ExtensionClass-related packages
==================================================
ExtensionClass
--------------
This package provides a metaclass that allows classes implemented in
extension modules to be subclassed in Python. Unless you need
ExtensionClasses for legacy applications (e.g. Zope 2), you probably
want to use Python's new-style classes (available since Python 2.2).
ComputedAttribute
-----------------
This package provides a way to attach attributes to an
``ExtensionClass`` or instance that are computed by calling a
callable. This works very much like ``property`` known from new-style
classes, except that a ``ComputedAttribute`` can also be attached to
an instance and that it honours ExtensionClass semantics (which is
useful for retaining Acquisition wrappers, for example).
MethodObject
------------
This package lets you attach additional "methods" to ExtensionClasses.
These "methods" are actually implemented by subclassing the
``MethodObject.Method`` class and implementing the ``__call__`` method
there. Instances of those classes will be bound to the instances
they're attached to and will receive that instance object as a first
parameter (after ``self``).
Changelog
=========
2.13.2 (2010-06-16)
-------------------
- LP #587760: Handle tp_basicsize correctly.
2.13.1 (2010-04-03)
-------------------
- Removed undeclared testing dependency on zope.testing.
- Removed cruft in ``pickle/pickle.c`` related to removed ``__getnewargs__``.
2.13.0 (2010-02-22)
-------------------
- Avoid defining ``__getnewargs__`` as not to defeat the ZODB persistent
reference optimization. Refs https://bugs.launchpad.net/zope2/+bug/143657.
In order to take advantage of this optimization, you need to re-save your
objects.
2.12.0 (2010-02-14)
-------------------
- Removed old build artifacts and some metadata cleanup.
- Added support for method cache in ExtensionClass. Patch contributed by
Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182.
2.11.3 (2009-08-02)
-------------------
- Further 64-bit fixes (Python 2.4 compatibility).
2.11.2 (2009-08-02)
-------------------
- Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See
http://www.python.org/dev/peps/pep-0353/ for details.
2.11.1 (2009-02-19)
-------------------
- Initial egg release.
