From "Design Patterns" pg. 215:
You can make[8] generic proxies in Smalltalk by defining classes whose superclass is nil and defining the doesNotUnderstand: method to handle messages. [8] Almost all classes ultimately have Object as their superclass. Hence this is the same as saying "defining a class that doesn't have Object as its superclass." but in Pharo: nil subclass: #MyProxy instanceVariableNames: '' classVariableNames: '' category: '' -> MessageNotUnderstood: receiver of "subclass:instanceVariableNames:classVariableNames:category:" is nil ----- Cheers, Sean -- View this message in context: http://forum.world.st/Proxies-Subclassing-nil-tp4816443.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
