EOGenerator (an awesome tool!)
EOGenerator
is a powerful tool and worthwhile incorporating. I just did for the first time
on a new project. While it is fresh in my mind I put together a quick start
guide....
EOGenerator
is freeware from the great folks at Rubicode . In a nutshell,
it saves you time and energy because if you you use it, you will have to write
less java code. It implements the Generation Gap
Design pattern for your EOModel's
entities.
Practical WebObjects recommends it. David LeBer recommends it. Jonathon "Wolf" Rentzsch at rentzsch recommends it.
Download it, expand it. I used Jonathon's templates as a basis for mine. Available here (Thanks Jonanthon) ....

Some notes on Jon's templates that can be fixed if you learn MiscMerge and update the templates (but until then, manually fix these in generated code). Also these are only an issue in the case of inheritance hierarchies:
- The subclass for abstract entities is not abstract itself and it should be
- Base classes get a "localInstance" method which throws a compile error on the subclasses because the return types are different signature.
To quickstart, use David LeBer's command line arguments as a guide.
On my Powerbook, I copied eogenerator executable to /usr/bin (to save me having to modify my class paths yet again or to save me having to type long path-based commands!). My command looked something like this for my current project:
eogenerator -model /Users/kieran/DevProjects/Cheetah/Code/cheetah/cheetah.eomodeld -destination /Users/kieran/DevProjects/Cheetah/Code/cheetah -subclassDestination /Users/kieran/DevProjects/Cheetah/Code/cheetah -templatedir /Users/kieran/Applications/EOGenerator/MyTemplates -javaTemplate JavaSourceEOF52.eotemplate -subclassJavaTemplate JavaSubclassSourceEOF5.eotemplate -verbose -java
After gnerating the java files, simply add the all to the classes category of your XCode project (if you use XCode)
