I have to modify CMFSetup's type information import/export
(typeinfo.py).
Currently, to discriminate on ti types on export, it does:
if isinstance( ti, FactoryTypeInformation ):
...
elif isinstance( ti, ScriptableTypeInformation ):
...
Because I have other TypeInformation classes, with different
properties, I'll have to use some kind of registry. Anyone has
special needs here, before I commit an implementation? I think
I'll do a registry that discriminates on ti.meta_type.
Note that my ti class is a subclass of FactoryTypeInformation, so
the isinstance test above is not enough in any case.
In the long run we might need a registry for meta_type or interface
specific import/export handlers.
But if you just need support for different PropertyManager
properties, I'd propose an other solution:
utils.ConfiguratorBase has some methods for generic property
support. The typeinfo handlers could use that code in a similar way
as the site properties handlers or the handlers for the newstyle
Actions on HEAD.
The property support works with any set of properties, so there
would be no need to write new handlers for customized typeinfo
classes.
Ok that's another option that suits me too.
But it will change a bit the XML format. I don't have a problem with
that, but I hope people are OK with a backport to the 1.5 branch of
such changes.
