Members

Summary

An object adapting a on_trait_change callback into an observe callback.

Extended Summary

The comparison operator __eq__ is implemented to enable removal of wrapped callbacks.

__hash__ is deliberately left unset: instances compare equal to the callback they wrap, so no hash could stay consistent with __eq__.
