3 -If you've ever used EOModeler's Java source code generator, you know how much of a pain it can be when you make changes to your model objects and have to merge changes in later. One solution for this is to use [[EOGenerator>>http://www.rubicode.com/Software/EOGenerator/]], an application developed by Rubicode Software, which uses the Generation Gap pattern to create your Java files from your EOModels. EOGenerator produces TWO java files for each Entity rather than one. Take the example of a Person entity. The first java file is //Person.java, which contains all of the autogenerated methods. The second java file is Person.java, and Person extends //Person. The second file is where you place all of your customizations. Any time your model changes, only your //Xxx.java files are updated, and your customizations are left untouched. Additionally, EOGenerator allows for the creation of extensive custom templates for your files, which provides the ability to place convenience methods in your //Xxx.java files.

7 7  There are several advantages to using EOGenerator over EOModeler's default Java file generation and merging with FileMerge.
8 8  
9 9  * EOGenerator uses the Generation Gap pattern, which provides a much cleaner separation of autogenerated vs customized code with no need to deal with merging at all. There are border cases with FileMerge that can cause you to deal with annoying conflicts.

10 10  * EOGenerator uses the MiscMerge language for its templates. This allows you to extend the core templates with extensive customizations (see the EOGenerator Mods section below), better supporting your own custom development process and workflow.
11 11  * As David LaBer put it, "all the cool kids use it - and we all know looking cool is the **most** important criteria".

28 28  Voila. EOGenerator will spit out your Java files for you. Let's break down the commands you can pass in:
29 29  
30 -* --define--EOGenericRecord <class>, allows you to specify the //Person class's superclass. For instance, if you use Project Wonder, you would specify --define--EOGenericRecord er.extensions.ERXGenericRecord//
31 -* --destination <path>, the folder that //Person.java//--//style java files will be produced in (the non-editable files)//
32 -* --java, produce java files--
33 -* --javaTemplate <filename>, the name of the Java template to use inside of the template dir (//Person)//--
34 -* --model <path>, Passes in the path of a .eomodeld you would like to generate Java files for. You can actually include multiple --model commands on the commandline
35 -* --packagedirs, produce package directory for any package statements defined in your Java files (not necessary if you don't specify package names on your entities. By the way, you should specify packages on your entities :) )--
36 -* --refmodel <path>, Passes in the path of an .eomodeld that is required for generating Java files, but that won't actually have Java files generated for it. For instance, you should --refmodel any prototypes, or any models in other frameworks that you depend on
37 -* --subclassDestination <path>, the folder that Person.java--style java files will be produced in (the editable files)
38 -* --subclassJavaTemplate <filename>, the name of the Java subclass template to use inside of the template dir (Person)--
39 -* --templatedir <path>, the path to the folder that contains EOGenerator templates--
40 -* --verbose, turn on verbose output--
40 +* define-EOGenericRecord <class>, allows you to specify the Person class's superclass. For instance, if you use Project Wonder, you would specify define-EOGenericRecord er.extensions.ERXGenericRecord
