class Finalizable

core :: Finalizable

An object needing finalization

It is recommended to sub-class Finalizable only on simple objects directly managing a limited resource. This use case is common when wrapping an extern instance with a standard object.

Introduced properties

fun finalize

core :: Finalizable :: finalize

Liberate any resources held by self before the memory holding self is freed

	# This method is invoked by the GC during a garbage collection when `self`

	# to use attributes of this instances, unless theses attributes are finalizable as well
