I didn't explain myself clearly enough:
Here's an example of 'quasi-properties', aka 'direct access', and no
docstrings:
class Transaction(object):
def __init__(self, app, ...):
self.application = app
Here it is again with true properties and a docstring:
class Transaction(object):
def __init__(self, app, ...):
self._application = app
def _getApp(self):
return self._application
application = property(_getApp, None, None, 'docstring')
This 'quasi-properties' approach is faster than the 'accessor-method'
approach that Webware currently uses. The true 'properties' style is
the equivalent to, or possibly slower than, accessor methods.
