You can add instances of the extension point named com.ibm.xtools.transform.core.transformationExtensions
to existing Eclipse plug-ins. This extension point facilitates the
configuration of extensions to transformations that are registered
with the transformation service.
Before you begin
You must open the plug-in manifest file.
About this task
A transformation extension is the mechanism that enables
you to add rules, content extractors, or transforms to an existing
transformation. Typically, you create one instance of a transformation
extension point in a plug-in; although, you can add multiple instances
depending on how you want to group the transformation extensions in
the plug-in.
Procedure
- In the plug-in manifest editor, on the Extensions tab,
beside the pane in the All Extensions area,
click Add.
- In the New Extension wizard, on the Extension Point Selection
page, in the Extension Point Selection window, on the Extension
Points tab, click com.ibm.xtools.transform.core.transformationExtensions and
complete one of the following steps:
- To create an instance of a transformation extension point;
provide values for a new transformation extension element; and add
rules, content extractors, and transforms to the transformation extension
element; in the Available templates for xtools transformation extensions
pane, click Transformation Extensions and complete
the remaining pages in the Transformation Extensions wizard. The src/m/n.rules
folder and the src/m/n.extractors
folder, where m represents the project name and n represents
the name of the transformation extension, contain the Java™ implementations of the rules and extractors
that you define by using the wizard.
Note: For more information about the other
fields on this page and the remaining pages in the wizard, see the

for more information about the other fields on this page and the remaining
pages in the wizard, see the context-sensitive help by pressing Shift+F1 when

- To create an instance of a transformation extension point,
a Transformation Extension element, and an ExtendTransform element,
all with default names, click Finish.
Results
An extension point named com.ibm.xtools.transform.core.transformationExtensions
and a corresponding transformation extension element are added to
the plug-in manifest file, and are displayed on the
Extensions tab,
in the pane under the
All Extensions area.
