The instance side equivalent of canUnderstand: is #respondsTo:.. #includesSelector: is class side too but does not look in superclasses. So you have: Integer respondsTo: #readFrom: --> true Integer class canUnderstand: #readFrom: --> true Integer class includesSelector: #readFrom: --> true > > On 2013-04-20, at 20:01, Milan Mimica <milan.mim...@gmail.com> wrote: > >> How come this evaluates to false? >> Integer canUnderstand: #readFrom: --> false >> Integer includesSelector: #readFrom: --> false >> >> However, it does implement the method. >> Integer readFrom: '1' readStream. --> 1 >> >> >> -- >> Milan Mimica >> http://sparklet.sf.net > >
