- //+ Name DwMailbox -- Class representing an RFC-822 mailbox
- //+ Description
- //. RFC-822 defines a {\it mailbox} as an entity that can be the recipient
- //. of a message. A mailbox is more specific than an {\it address}, which
- //. may be either a mailbox or a {\it group}. An RFC-822 mailbox contains
- //. a full name, a {\it local-part}, an optional {\it route}, and a
- //. {\it domain}. For example, in the mailbox
- //.
- //. Joe Schmoe <jschmoe@aol.com>
- //.
- //. "Joe Schmoe" is the full name, "jschmoe" is the local-part, and
- //. "aol.com" is the domain. The optional route is rarely seen in current
- //. usage, and is deprecated according to RFC-1123.
- //.
- //. In MIME++, an RFC-822 mailbox is represented by a {\tt DwMailbox} object.
- //. {\tt DwMailbox} is a subclass of {\tt DwAddress}, which reflects the
- //. fact that a mailbox is also an address. A {\tt DwMailbox} contains
- //. strings representing the full name, local-part, route, and domain
- //. of a mailbox.
- //.
- //. In the tree (broken-down) representation of message, a {\tt DwMailbox}
- //. object may be only a leaf node, having a parent but no child nodes.
- //. Its parent node must be a {\tt DwField}, a {\tt DwAddressList}, or a
- //. {\tt DwMailboxList} object.
- //.
- //. {\tt DwMailbox} has member functions for getting or setting the strings
- //. it contains.
- //.
- //. {\tt DwMailbox} object can be included in a list of {\tt DwMailbox}
- //. objects. To get the next {\tt DwMailbox} object in a list, use the
- //. inherited member function {\tt DwAddress::Next()}.

- public:
-
- DwMailbox();
- DwMailbox(const DwMailbox& aMailbox);
- DwMailbox(const DwString& aStr, DwMessageComponent* aParent=0);
- //. The first constructor is the default constructor, which sets the
- //. {\tt DwMailbox} object's string representation to the empty string
- //. and sets its parent to {\tt NULL}.
- //.
- //. The second constructor is the copy constructor, which performs
- //. a deep copy of {\tt aMailbox}.
- //. The parent of the new {\tt DwMailbox} is set to {\tt NULL}.
- //.
- //. The third constructor copies {\tt aStr} to the {\tt DwMailbox}
- //. object's string representation and sets {\tt aParent} as its parent.
- //. The virtual member function {\tt Parse()} should be called immediately
- //. after this constructor in order to parse the string representation.
- //. Unless it is {\tt NULL}, {\tt aParent} should point to an object of a class
- //. derived from {\tt DwField}.
-
- virtual ~DwMailbox();
-
- const DwMailbox& operator = (const DwMailbox& aMailbox);
- //. This is the assignment operator, which performs a deep copy of
- //. {\tt aMailbox}. The parent node of the {\tt DwMailbox} object
- //. is not changed.
-
- virtual void Parse();
- //. This virtual function, inherited from {\tt DwMessageComponent},
- //. executes the parse method for {\tt DwMailbox} objects. The parse
- //. method creates or updates the broken-down representation from the
- //. string representation. For {\tt DwMailbox} objects, the parse
- //. method parses the string representation into the substrings for
- //. the full name, local-part, route, and domain.
- //.
- //. You should call this member function after you set or modify the
- //. string representation, and before you retrieve the full name,
- //. local-part, route, or domain.
- //.
- //. This function clears the is-modified flag.
-
- virtual void Assemble();
- //. This virtual function, inherited from {\tt DwMessageComponent},
- //. executes the assemble method for {\tt DwMailbox} objects. The
- //. assemble method creates or updates the string representation from
- //. the broken-down representation. For {\tt DwMailbox} objects, the
- //. assemble method builds the string representation from the full
- //. name, local-part, route, and domain strings.
- //.
- //. You should call this member function after you modify the full
- //. name, local-part, route, or domain, and before you retrieve the
- //. string representation.
- //.
- //. This function clears the is-modified flag.
-
- virtual DwMessageComponent* Clone() const;
- //. This virtual function, inherited from {\tt DwMessageComponent},
- //. creates a new {\tt DwMailbox} on the free store that has the same
- //. value as this {\tt DwMailbox} object. The basic idea is that of
- //. a virtual copy constructor.
-
- const DwString& FullName() const;
- //. Returns the full name for this {\tt DwMailbox} object.
-
- void SetFullName(const DwString& aFullName);

- //. Returns the route for this {\tt DwMailbox} object.
-
- void SetRoute(const DwString& aRoute);
- //. Sets the route for this {\tt DwMailbox} object.
-
- const DwString& LocalPart() const;
- //. Returns the local-part for this {\tt DwMailbox} object.
-
- void SetLocalPart(const DwString& aLocalPart);
- //. Sets the local-part for this {\tt DwMailbox} object.
-
- const DwString& Domain() const;
- //. Returns the domain for this {\tt DwMailbox} object.
-
- void SetDomain(const DwString& aDomain);
- //. Sets the domain for this {\tt DwMailbox} object.
-
- static DwMailbox* NewMailbox(const DwString& aStr, DwMessageComponent*
- aParent);
- //. Creates a new {\tt DwMailbox} object on the free store.
- //. If the static data member {\tt sNewMailbox} is {\tt NULL},
- //. this member function will create a new {\tt DwMailbox}
- //. and return it. Otherwise, {\tt NewMailbox()} will call
- //. the user-supplied function pointed to by {\tt sNewMailbox},
- //. which is assumed to return an object from a class derived from
- //. {\tt DwMailbox}, and return that object.
-
- //+ Var sNewMailbox
- static DwMailbox* (*sNewMailbox)(const DwString&, DwMessageComponent*);

- //. from {\tt DwMailbox}.
