public abstract class MediaTypeHandler
Base class of all media type handlers. It defines the three basic methods to be implemented by all media type handlers. This is initialized with the objects required for handling media type specific operations, so that extending media type handlers can easily access them. One such object is the instance of the MediaTypeManager.
