Hi squeakers,
I have to build a lite code for home work.
The objective is to gave to user a possibility to store his sport
performance.
So I have design a Class Performance(with PerformanceCollection) and I
wanted to let things like TimeLaps, Date, Distance, and so on.
for a later implementation (if we wanted to add others).
So I provide a Measure abstract class.
Hence I add a dictionary in my Performance with the class for key and
the instance for value:
for example:
Performance>>addMeasure: aMeasure
dictionaryOfMesure at: aMeasure class put: aMeasure
Now I have to bring them in a Seaside UI so I guess that Visitor Pattern
( ;-) ) can help me but my complex structure mess my brain.
So I ask you if you think that can be possible(and how) or other pattern
can be more suitable for this problem.
Thank you for your attention (:
