EOGenerator template wrapping EOUtilities

  • Subject: EOGenerator template wrapping EOUtilities
  • From: Greg <email@hidden>
  • Date: Fri, 23 Sep 2005 14:16:30 +1000
I have been doing a post-mortem of my current development cycle and have been looking at ways to increase the readability of the code in my components. One of the things I have noticed is that I use EOUtilities quite a lot and always cast the returned EO. I decided to modify my EOGenerator template to wrap most of the EOUtilities methods so that you don't have to cast anymore.

I has to modify eogenerator by adding a new string method lastLetter to improve the grammar of the generated method names. This is for checking if an identifier ends with an 's' as to whether or not put an 's' or 'es' on method names. If you don't want to modify eogenerator you can easily remove the parts <$if classNameWithoutPackage.lowercaseString.lastLetter eq 's'$>es<$else $>s<$endif$>

I thought I would share my code as so many others on here do the same. I wished I had done this at the start of my project, but like a lot of others I was a newbie, so I made my code more readable. If people want my complete template just let me know and I will send it on to you.

Regards,
Greg
