- //+ Name DwAddress -- Abstract class representing an RFC-822 address
- //+ Description
- //. {\tt DwAddress} represents an {\it address} as described in RFC-822.
- //. You may not instantiate objects of type {\tt DwAddress}, since
- //. {\tt DwAddress} is an abstract base class. Instead, you must instantiate
- //. objects of type {\tt DwMailbox} or {\tt DwGroup}, which are subclasses
- //. of {\tt DwAddress}.
- //.
- //. To determine the actual type of a {\tt DwAddress} object, you can use
- //. the member functions {\tt IsMailbox()} and {\tt IsGroup()}.
- //.
- //. If the string representation assigned to a {\tt DwAddress} is improperly
- //. formed, the parse method will fail. To determine if the parse method
- //. failed, call the member function {\tt IsValid()}.
- //.
- //. A {\tt DwAddress} object can be contained in list. To get the next
- //. {\tt DwAddress} object in the list, call the member function {\tt Next()}.

- //. The virtual member function {\tt Parse()} should be called immediately
