get_marshalling_data(self)

Return marshalling data for my attributes.

To be implemented by derived classes.

The returned marshalling data is a dictionary object that
contains relatively anonymous data which represents the object
to be marshalled. The dictionary is composed by derived
classes and must look as follows:

::

   {
      'generating_class': <class object of generating object>,
      'versions': <versions of contributions>,
      'attributes': <dictionary with direct attributes key/value pairs>,
   }

Called indirectly by `__getstate__`.

Overrides:

libconfix.core.repo.marshalling.Marshallable.get_marshalling_data (inherited documentation)

set_marshalling_data(self, data)

(To be documented)

Overrides:

unique_key(self)

Unique key to easily determine object equivalence. Used to
index BuildInformation objects, and to eventually sort out
duplicates.
