Hi all,
Monticello has a problem with this class construction:
ProtoObject subclass: #MyClass instanceVariableNames: 'object' classVariableNames: '' poolDictionaries: '' category: 'MyClasses. MyClass superclass: nil
It forgets the last line with superclass specification.
I'm using it for proxy objects. Instances of MyClass have one variable to store a real receiver of messages. MyClass resends messages using doesNotUnderstand mechanism.
doesNotUnderstand: aMessage
^ aMessage sendTo: object.
It works well but there is one problem - Squeak uses optimalization of some message calls. For example, message #class is never called, because Squeak uses special bytecode 199 (bytecodePrimClass). Real class of proxy object is returned instead of receiver class.
Message #isVariable returns wrong value for arrays, large integers etc. So I have made a variable subclass of MyClass and I use it for proxy object of variable receivers. It works well too.
I used this proxy objects for a dictionary and its instance variables including tally. This variable stores a size of dictionary. When Squeak makes a copy of dictionary array, he sends tally like a parameter in constructor of new array, but primitive method fails. VM wants an integer instance strictly.
Any ideas?
