Item was removed: - ----- Method: Dictionary>>fasterKeys (in category 'accessing') ----- - fasterKeys - "Contrary to old version of #keys, this method returned an Array rather than a Set. - This was faster because no lookup: was performed. - But now, #keys also return an Array, so don't use #fasterKeys anymore." - - self deprecated: 'use #keys'. - - ^self keys. - !
Item was removed: - ----- Method: Dictionary>>keyForIdentity: (in category 'accessing') ----- - keyForIdentity: anObject - "If anObject is one of the values of the receive, return its key, else return nil. Contrast #keyAtValue: in which there is only an equality check, here there is an identity check" - - self deprecated: 'Use #keyAtIdentityValue:ifAbsent:'. - ^self keyAtIdentityValue: anObject ifAbsent: nil!
