| − | ==The Simple Purchase Order Model==
| + | |
| − | To generate the EMF editor we first need a Ecore model. We will use the Simple Purchase Order model (file <tt>SimplePO.ecore</tt>) that is also used in the EMF book. In an UML Editor this model looks as depicted below:

| − | ==The Code Generation Model==
| + | |
| − | To generate code from the <tt>SimplePO.ecore</tt> model we first need to create a corresponding code generation model (file <tt>SimplePO.genmodel</tt>) for storing the code generation customization data.
| + | |
| − | Assumed you have all the EMF plugins installed in your Eclipse environment you can do this by a right click on the <tt>SimplePO.ecore</tt> file in the Package Explorer:
| + | |
| − | <center>[[Image:CreateGenModel1.gif]]</center>
| + | |
| − | Select the EMF Model wizard:
| + | |
| − | <center>[[Image:CreateGenModel2.gif]]</center>
| + | |
| − | Click the <b>Next</b> button two times:<br>
| + | |
| − | <center>[[Image:CreateGenModel3.gif]] [[Image:CreateGenModel4.gif]]</center><br>
| + | |
| − | Press the <b>Load</b> button and the <b>Next</b> button afterwards:<br>
| + | |
| − | <center>[[Image:CreateGenModel5.gif]]</center><br>
| + | |
| − | A click on the <b>Finish</b> button finally creates the <tt>SimplePO.genmodel</tt> file.<br>
| + | |
| − | <center>[[Image:CreateGenModel6.gif]]</center><br>
| + | |
| − | The code generation model allows you to customize the code generation. E.g. the properties
| + | |
| − | <tt>Model Directory</tt>, <tt>Editor Directory</tt>, and <tt>Edit Directory</tt> determine into which folder the model, editor and edit code is generated.<br>
| + | |
| − | <center>[[Image:CodeGenerationPaths.gif]]</center>
| + | |
| − | ==Generating the Code==
| + | |
| − | To generate the code for the model, edit and editor plugin simply do a right click on the root element of the <tt>SimplePO.genmodel</tt> and select <b>Generate All</b><br>
| + | |
| − | <center>[[Image:GenerateCode.gif]]</center>
| + | |
| − | This generates four plugin projects and appropriate code into the directories specified in the code generation model. In this example the <tt>SimplePO</tt>, <tt>SimplePO.edit</tt>, <tt>SimplePO.editor</tt> and the <tt>SimplePO.test</tt> plugin project directories.

| + | |
| − | ==Running the Editor==
| + | |
| − | By right clicking on the <tt>SimplePO.editor</tt> project directory and selecting <b><Run As></b> <b><Eclipse Application></b> the just generated editor is started in a new Eclipse instance (this might take some seconds).
| + | |
| − | <center>[[Image:RunTheEditor.gif]]</center>
| + | |
| − | The new Eclipse instance includes the generated plugins <tt>SimplePO Model</tt>, <tt>SimplePO Edit Support</tt> and <tt>SimplePO Editor</tt> as you can see by going into the <b><Help> <About Eclipse SDK></b> window and pressing the <b><Plug-in Details></b> button.
