Replace conditional statement with Polymorphism

[Doug Easterbrook]

a number of helpful listers focused on the actual algorithm.


to give you some sort of isolation and put that function in one spot, so you can easily fix it.


I’d create a method in your report superclass with parameter ‘pColLength’.      let call it $getPixel


then you can call it anywhere, in any report….  with the data in one spot

eg


$cinst.$getPixel(colLength).




ever report would have the same function, since its in a superclass, giving you a single place for the code.



and, should you want to over ride it in any one report, you can over ride  that function to have one report do it differently.



thats how I’d structure the code.


as for the actual algorithm….    lots of ideas there.
