- * Delegate used to provide new implementation of a select few methods of {@link Fragment}
- *
- * Through the layoutlib_create tool, the original methods of Fragment have been replaced
- * by calls to methods of the same name in this delegate class.
- *
- * The methods being re-implemented are the ones responsible for instantiating Fragment objects.
- * Because the classes of these objects are found in the project, these methods need access to
- * {@link IProjectCallback} object. They are however static methods, so the callback is set
- * before the inflation through {@link #setProjectCallback(IProjectCallback)}.
