Extension Contribution

This example plugin holds no GUI. It just extends the Extension Point Definition plugin.

Through the extension of the Extension Point Definition plugin two functionalities are added by implementing the minimal IChangeText interface of the plugin.

In the plugin.xml file of the plugin the extensions are defined as follows:

The extension point ID in the plugin.xml matches the ID of the extension point and is therefore found by the registry as a valid extension. A description is given for each extension although the schema for the extension point allows an extension without a description (<element ref="description" minoccurs="0" maxoccurs="1">).

The GUI now holds two buttons that change the input text of the user to upper or lower case. This is done by two simple methods.
