Exception when using db.Collector about revitpythonwrapper

[gtalarico]

Thanks for pointing this out. I completely forgot to run my tests against < 2017.
I will think about an elegant way of handling these API breaking changes for better multi version support and add it to the next version.

In the meantime, you can modify your FilterdElementCollector to work.

def __len__(self):
    """ Returns length of collector.elements """
    # return self._collector.GetElementCount()  # 2016+ only
    return len(self.elements) # This will should work, but my gut is that the built in performs better

Ps: I have not tested this as I don't have 2015 at home, if you decide to test it out, please let me know if it works.

@gtalarico I assume you meant len(self.elements) as len([self.elements]) will always be 1?

[gtalarico]

You are right @mostaphaRoudsari thanks
I will edit the post for others

@gtalarico It works seamlessly. Thanks for your reply.

    def __len__(self):
        """ Returns length of collector.elements """
        # return self._collector.GetElementCount()
        return len(self.elements)

>>> from rpw import db
>>> db.Collector(of_class="Wall")
<rpw:Collector % ..DB.FilteredElementCollector | count:511>
