Docs For Class HierarchyException

Description

OsidException or one of its subclasses is thrown by all methods of all

interfaces of an Open Service Interface Definition (OSID). This requires the caller of an OSID package method handle the OsidException. Since the application using an OSID can not determine where an implementation method will ultimately execute, it must assume a worst case scenerio and protect itself. OSID Implementations should throw their own subclasses of OsidException and limit exception messages to those predefined by their own OsidException or its superclasses. This approach to exception messages allows Applications and OSID implementations using an OsidException's predefined messages to handle exceptions in an interoperable way.
