Just use The God's Hammer Dispatch (AKA Non-intuitive way of programming
for those who don't think in objects ;) :
fillRectangle: aRectangle basicFillStyle: aFillStyle
"Fill the given rectangle with the given, non-composite, fill style."
| pattern |
(aFillStyle isKindOf: InfiniteForm) ifTrue: [
^self infiniteFillRectangle: aRectangle fillStyle: aFillStyle
].
=>
fillRectangle: aRectangle basicFillStyle: aFillStyle
"Fill the given rectangle with the given, non-composite, fill style."
^ aFillStyle fillRectangle: aRectangle onCanvas: self
..and then after refactoring it will look exactly how Athens doing it,
because if you rename fill style with "paint" and rectangle with "shape"
you will see it :)
