Hi everyone.
I've been fighting with this for a while now. So I mail the list for a
suggestion.
I have a `Variable` class wich I subclass from OOBTree, because I need a
dictionary with the min, max options that OOBTree methods give. My object is
supposed to store datetime.datetime instances as keys and floats numbers as
values. eg: temperature[datetime(2007, 4, 6, 12, 8)] = 25.8
I didn't use BTreeContainer because only takes strings as keys, and I don't
want to map datetime to strings and back.
Here's my class definition:
class Variable(OOBTree, Contained):
implements(IVariable, IAttributeAnnotatable)
name = None
units = None
class Variable(Persistent, Contained):
def __init__(self):
self.__mydata = OOBTree()
def keys(self, min, max ....):
return self.__mydata.keys(min, max, ....)
For example see implementations in "zope/app/container/sample.py"
