Validating transformation properties

You can implement the validateContext method in a TransformationProvider class to validate the properties that you add to a transformation.

Before you begin

You must have a plug-in manifest file open in the manifest editor. The manifest file must contain an instance of the transformation provider extension point, a transformation provider element, and a transformation.

About this task

To enable the validation of properties in a transformation:

Procedure

  1. On the Extensions tab, in the All Extensions area, click a TransformationProvider element.
  2. In the Extension Element Details area, click class. The Java file editor opens.
  3. In the Java file editor, in the transformation provider class, add the validation code for the validateContext() method. For more information about this method, which is contained in the class named com.ibm.xtools.transform.core.AbstractTransformationProvider, see the Rational® Transformation Developer Guide.
    Note: Some information, such as links to Eclipse documentation or to developer guides, is available only from the help topics that are installed with the product.
  4. Click File > Save.

Results

The validation code is invoked the next time that the transformation runs.
