I would like to hear opinions on small amounts of code replication within methods

  • 0

I would like to hear opinions on small amounts of code replication within methods that check for the same condition e.g.

While(condition){ ...... do x   }

Normally if there was any of this kind of replication I would refactor the code as it can make versioning a nightmare, what if the condition changes for example you have to change every instance, not a nice job to do. However what if the condition is relatively simple and is only used within say 3 methods is it wise to refactor,

So in summary where do people draw the line at refactoring code?

  1. Refactoring is not free. Any change to the code can introduce bugs. So every concious developer thinks about whether he has time to carefully examine the changes and in many cases decides not to refactor.
