Pharo Issue Tracker - Manuscript (Case [Issue]21570) Kernel - The system should not decide if a class is abstract or not

Manuscript Notification

	Guillermo Polito opened Case 21570: The system should not decide if a class is abstract or not and assigned it to Everyone: Bug in Kernel: 1. Pharo Image • You are subscribed to this case

The current implementation of #isAbstract

isAbstract

self withAllSuperclassesDo: [ :eachClass |
eachClass methodsDo: [ :eachMethod |
(eachMethod isAbstract and: [ (self lookupSelector: eachMethod selector) isAbstract ])
ifTrue: [ ^true ]]].

^false

leads to a lot of false positives.

A class is abstract by design, not by implementation. This should probably be replaced by something like #isFullyImplemented

	Priority: 3 – Must Fix		Status: Work Needed
	Assigned to: Everyone		Milestone: Later
