This interface should never be used directly in any hand-written code (except in FinalizeTrigger.java). It should only appear in automatically generated fooDerived-classes. To use finalizers in hand-written classes read the instructions at org.python.core.finalization.FinalizablePyObject.

Method Summary

Modifier and Type	Method and Description
public void	__del_derived__() `__del_builtin__` is the built-in's own finalizer, while `__del_derived__` refers to an instance's in-dict `__del__`.

Method Detail

__del_derived__ back to summary

__del_derived__	back to summary
public void __del_derived__() `__del_builtin__` is the built-in's own finalizer, while `__del_derived__` refers to an instance's in-dict `__del__`. A FinalizeTrigger calls `__del_derived__` first and - if existent - `__del_builtin__` after that. A plain `__del__` would behave as overridden by `__del_derived__`, i.e. won't be called if the type implements `FinalizablePyObjectDerived` while `__del_builtin__` is called in any case.
