Get all the inverse attributes' names

[lorinma]

Hi Thomas,

I'm using ifcopenshell-python, I can get the inverse attribute's value by
giving the attribute's name, but is it possible to get all the inverse
attributes' name of an entity?

e.g., given a IfcShapeRepresentation entity, list the
names: [RepresentationMap，LayerAssignments，OfProductRepresentation]

Thanks!

Hi,

In principal yes, but with all the development effort in this area lately it is not very stable. Are you using binaries from the website or you compiled your own?

Your best bet is probably to try the following:

>>> import ifcopenshell
>>> f = ifcopenshell.open()
>>> w = f.createIfcWallStandardCase()
>>> w.wrapped_data.get_inverse_attribute_names()
(u'ConnectedFrom', u'ConnectedTo', u'ContainedInStructure', u'Decomposes', u'Fil
lsVoids', u'HasAssignments', u'HasAssociations', u'HasCoverings', u'HasOpenings'
, u'HasPorts', u'HasProjections', u'HasStructuralMember', u'IsConnectionRealizat
ion', u'IsDecomposedBy', u'IsDefinedBy', u'ProvidesBoundaries', u'ReferencedBy',
 u'ReferencedInStructures')

Hope that helps,

Kind regards,
Thomas

Hi Thomas,
Thanks for your reply.
I'm using IfcOpenShell-python for python 3.4 64bit Linux from the website.
It seems there's no get_inverse_attribute_names()
Should I compile the current master version on github?
Thanks!
