Hi!

It would be great to get feedback from you guys. 

We have the class TRConstraint that allows for roassal elements to be aligned (cf Section 10 in https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/Roassal/0104-Roassal.html). 

Currently, you can write: 

TRConstraint use: centralDot alignFromTop: negativeElements

Which align all the elements contained in the collection negativeElements against a fix point, centralDot.

It looks pretty easy to read. However, the class TRConstraint has many methods (alignFromBottom:, alignFromLeft:, use: aShape alignFromBottom: shapes, …) which are essentially all duplicated code.

So, I though about creating a compact class, called RTAlignment. You can now write:

RTAlignment new elements: negativeElements; fixedElement: centralDot; top

But, I find that less nice to read. Any opinion?

Cheers,

Alexandre
