role Metamodel::Finalization

Metaobject supporting object finalization

DESTROY

role Metamodel::Finalization { ... }

This role takes care that DESTROY submethods are called (if they exist) when an object is garbage-collected.

Methods

method setup_finalization

method setup_finalization(Metamodel::Finalization:D: $obj)

Collects the DESTROY submethods from this class and all its superclasses, and marks the class as needing action on garbage collection.

A metamodel for a kind that implements finalization semantics must call this method at type composition time.

method destroyers

method destroyers(Metamodel::Finalization:D: $obj --> List:D)

Returns a list of all finalization methods.
