The extension point TopHeaderContentProvider is a java interface you can implement to provide content for the top header area of the novomind iAGENT Supervisor frontend.
Your plugin has to return a TopHeaderContent object.
TopHeaderContent contains a path to a custom JSF xhtml file that will be included in the novomind iAGENT Supervisor frontend. The path needs to be specified as an absolute path inside the
META-INF/views directory of your plugin jar file.
For a complete example take a look at the Hello World Supervisor Top Header App.
