cdrick a écrit :
or again
removeAll: aCollection
aCollection == self
ifTrue: [self removeAll: aCollection copy]
ifFalse: [aCollection do: [:each | self remove: each]].
Or maybe, if aCollection == self, a warning could be raised ?
What do you think ?
Cédrick
aCollection == self is not the only case that can fail.
Imagine i pass a wrapper collection on self, like a MappedCollection.
When i will change self with remove:, i will also change the argument
which is just a wrapper on self.
Hope my explanations are not too much confusing...
