extends java.lang.Object

A Dictionary contains information required by the IBM CardAgent. for accessing files, e.g. file paths, access conditions, offsets and sizes. AgentDictionary is the abstract base class of all dictionaries. Every individual concrete dictionary is a distinct subclass of AgentDictionary. Instances are not created. Rather the class has class methods only.
