EToys Overlap, OverlapAny
by Michael.Guckert＠t-online.de 03 Jun '06

03 Jun '06

Hi, I've experimented with overlap and opverlapAny. When exactly do they produce TRUE. Does overlapAny really mean that it fires on copies and siblings of the argument as well? I can't interpret the results of my experiments and need help. Thank Michael

dependency mechanism
by Chris Kassopulo 01 Jun '06

01 Jun '06

Greetings, The basic dependency example from "Smalltalk By Example" uses Visualworks changed:with and update:with:from: methods like this: price: aPrice | oldPrice | oldPrice := self price. price := aPrice. self changed: #price with: oldPrice update: aSymbol with: oldPrice from: aStock (aSymbol == #price) ifTrue: [Transcript cr; show: thisContext; tab; show: aSymbol; tab; nextPutAll: 'Price changed from: '; show: oldPrice; tab; nextPutAll: 'To: '; show: aStock price; flush] The problem is that Squeak only implements update:with: so the aStock price messaging doesn't work. My solution was to follow VW's implementation by making the following changes: Modified the changed:with: method to include from:. changed: anAspect with: anObject self dependents do: [:aDependent | aDependent update: anAspect with: anObject from: self] Added an update:with:from: method. update: anAspect with: anObject from: aSender ^ self update: anAspect with: anObject It took a while to see the problem and without looking at VW, I never would have been able to figure a way. Is my fix reasonable? VW also implements expressInterestIn:for:sendBack: and onChangeSend:to: methods. Anyone familiar with them and care to provide pointers on the possibility of implementing something similar in Squeak? Thanks, Chris
