Specifying custom classes to generate model-to-model transformation source code

You can refine how the transformation source code, also called implementation code, is generated by overriding the classes in the default transformation authoring framework.

About this task

By default, when you generate the transformation source code, for each generated transformation element, the generated code extends the classes in the default transformation framework. By overriding the default classes in the transformation authoring framework, you can customize the how the transformation implementation code is generated.

You can apply this preference to all projects in the workspace, or to specific projects.

Procedure

To apply this preference to all the projects in the workspace:
1. Click Window > Preferences > Modeling > Transformation > Transformation Mapping Framework.
2. For each transformation framework element to override, click the ellipsis button (...), and select a class that extends that transformation framework element.
3. Click Apply; then click OK.
To apply this preference to a new transformation mapping project:
1. Create a transformation mapping project.
2. In the New Transformation Authoring Project Using Transformation Mapping wizard, on the Transformation Source Code Generation Properties page, for each transformation framework element to override, click the ellipsis button (...), and select a class that extends that transformation framework element.
3. Complete the remaining pages in the wizard; then click Finish.
To apply this preference to an existing project:
1. In the Package Explorer view, right-click the transformation mapping project; then click Properties.
2. In the Properties for projectname window, click Transformation Mapping Framework.
3. For each transformation framework element to override, click the ellipsis button (...), and in the Class to use for transformation element window, select a class that extends that transformation framework element.
4. Click Apply; then click OK.
Note: If you override a default class at the workspace level, but want to revert to the default class when you generate the source code for a specific project, you must revert to the default class at the workspace level. You cannot revert to a default class to generate code for a specific project. After you generate the source code, to re-apply the overriding class, you must specify the custom class at the workspace level.
