function

traitlets.traitlets:observe_compat

source: /traitlets/traitlets.py:1173

Signature

def observe_compat(func: FuncT) → FuncT

Summary

Backward-compatibility shim decorator for observers

Extended Summary

Use with:

@observe('name') @observe_compat def _foo_changed(self, change): ...

With this, super()._foo_changed(self, name, old, new) in subclasses will still work. Allows adoption of new observer API without breaking subclasses that override and super.
