- Subclasses:
- MailcapCommandMap
- public abstract class CommandMap
- extends java.lang.Object
The CommandMap class provides an interface to the registry of

implementation included with this package (MailcapCommandMap) or
develop their own. Note that some of the methods in this class are
abstract.
