Specifying JET transformation configuration options

When you create a JET transformation project, default values are provided for the transformation entry point template, template loader classes, and other JET transformation properties. To specify different values for these properties, you must modify the extension element details in the plugin.xml file.

You must have a JET transformation project in your workspace.

To specify the implementation details of a JET transformation:

In the Project Explorer view, in the JET transformation project, right-click the plugin.xml file; then click Open.
Click the Extensions tab.
Expand the org.eclipse.jet.transform extension; then click (transform).
Edit the appropriate fields in the Extension Element Details area of the page.
1. In the startTemplate field, specify the project relative path to the JET file that contains the transformation implementation information. Typical values include template/control.jet or template/main.jet.
2. In the templateLoaderClass field, specify the fully qualified name of the Java™ class that loads the JET templates. This class is created by the JET compiler. This field is infrequently changed.
3. In the modelLoader field, specify how the Transformation Input resource, for example, a file, folder, or project, is converted into an in-memory model that the JET transformation can process. The default value is org.eclipse.jet.emfxml, which indicates that the resource should be loaded as an XML document. For other model types, including UML models, specify org.eclipse.jet.emf. If you do not specify a value, a model loader is selected based on the file extension of the input model, or by the value of the modelExtension attribute. The default value is blank, which is equivalent to org.eclipse.jet.emfxml. You can use the org.eclipse.jet.modelLoaders extension point to extend this value.
