ElementWithXSIType¶
- class pyvo.utils.xml.elements.ElementWithXSIType(*args, **kwargs)[source]¶
- Bases: - Element- An XML element that supports type dispatch through xsi:type. - When a class A is derived from this, it gains a decorator register_xsi_type, which classes derived from A can use to say “construct me rather than A when xsi:type has the value I’m putting in. - At this point we are doing no namespace processing in our XML parsing. Hence, we discard any prefixes both when registering and when matching. - We probably should do namespaces one day; astropy.utils.xml will presumably learn them when they add VO-DML support. Let’s revisit this when it’s there safely. Meanwhere, use canonical Registry prefixes (cf. RegTAP 1.1, sect. 5) everywhere in your code; these will continue to be safe no matter what. - Methods Summary - register_xsi_type(typename)- Decorator factory for registering subtypes. - Methods Documentation
