Programmatically duplicating the effects of Generate Model Code [message #1803115]

I am working on a module to automate a semi-manual process which currently includes the use of EMF to generate a large number of Java files based on a genmodel file (A sample.genmodel which is similar to the actual file is below. I have broken up the hyperlinks in the root XML tag).

Currently, in our manual process, we have to open the sample.genmodel file, right-click the root genPackage (named Zxyw), and click Generate Model Code. All of the necessary Java classes are then generated inside the folder
/somedirectory/src-gen/main/java

I would like to figure out the Java code necessary to achieve the same effect as clicking Generate Model Code. As mentioned above, this code generation is only part of a larger process, which is being automated though a Java program.

Thank you for your help and guidance on this.

sample.genmodel:

<?xml version="1.0" encoding="UTF-8"?>
<genmodel:GenModel xmlns:ecore="http: //www.eclipse.org/emf/2002/Ecore" xmlns:xmi="http: //www.omg.org/XMI" codeFormatting="true" complianceLevel="7.0" copyrightFields="false" dynamicTemplates="true" featureDelegation="Dynamic" importOrganizing="true" importerID="org.eclipse.emf.importer.ecore" modelDirectory="/somedirectory/src-gen/main/java" modelName="Zxyw" modelPluginID="modelPluginID" operationReflection="true" rootExtendsClass="org.eclipse.emf.ecore.impl.MinimalEObjectImpl$Container" xmi:version="2.0" xmlns:genmodel="http: //www.eclipse.org/emf/2002/GenModel">
<foreignModel>sample.ecore</foreignModel>
<genPackages basePackage="example.basepackage" disposableProviderFactory="true" ecorePackage="sample.ecore#/" prefix="Zxyw">
<nestedGenPackages basePackage="example.basepackage.sample" disposableProviderFactory="true" ecorePackage="sample.ecore#//enums" prefix="Enums">

<nestedGenPackages basePackage="example.basepackage.sample" disposableProviderFactory="true" ecorePackage="sample.ecore#//eventresults" prefix="Eventresults">

</nestedGenPackages>
</genPackages>
<genPackages prefix="Models" basePackage="example.basepackage" disposableProviderFactory="true"
loadInitialization="true" literalsInterface="false" ecorePackage="models.ecore#/">

</genPackages>
</genmodel:GenModel>

Hi

In Java, you can use EMF's Generator API.

Historically this kind of control was performed using Ant for which EMF provides Ant tasks. These are little used, painful to maintain and might fade away.

Much better to use MWE2, for which I developed the org.eclipse.ocl.examples.build.utilities.GenerateMo.del bean a few years ago. There is now org.eclipse.emf.mwe.utils.GenModelHelper, but I have never used it.
