	 *		For example an interface defined by <code>interface A {}</code>,
	 *		although obviously public, will be returned false by <code>Flags.isPublic(modifiers)</code>

	 *          direct parent of the type (for example, if the class is x.y.A$B$C then
	 *          the enclosing types are [A, B]. This is an empty array if the type
	 *          is a top-level type.

	 *          or a source file, this is the full path in the workspace to this resource. If the
	 *          resource is an archive (that is, a .zip file), the path is composed of 2 paths separated

	 *			 the first path is the full OS path to the archive (if it is an external archive), 
	 *			 or the workspace relative <code>IPath</code> to the archive (if it is an internal archive), 
	 * 		 the second path is the path to the resource inside the archive.
