- //+ Name DwGroup -- Class representing an RFC-822 address group
- //+ Description
- //. {\tt DwGroup} represents a {\it group} as described in RFC-822. A group
- //. contains a group name and a (possibly empty) list of {\it mailboxes}.
- //. In MIME++, a {\tt DwGroup} object contains a string for the group name
- //. and a {\tt DwMailboxList} object for the list of mailboxes.
- //.
- //. In the tree (broken-down) representation of message, a {\tt DwGroup}
- //. object may be only an intermediate node, having both a parent and a single
- //. child node. Its parent node must be a {\tt DwField} or a
- //. {\tt DwAddressList}. Its child is a {\tt DwMailboxList}.
- //.
- //. A {\tt DwGroup} is a {\tt DwAddress}, and therefore it can be included
- //. in a list of {\tt DwAddress} objects. To get the next {\tt DwAddress}
- //. object in a list, use the inherited member function
- //. {\tt DwAddress::Next()}.

- public:
-
- DwGroup();
- DwGroup(const DwGroup& aGroup);
- DwGroup(const DwString& aStr, DwMessageComponent* aParent=0);
- //. The first constructor is the default constructor, which sets the
- //. {\tt DwGroup} 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 aGroup}.
- //. The parent of the new {\tt DwGroup} object is set to {\tt NULL}.
- //.
- //. The third constructor copies {\tt aStr} to the {\tt DwGroup}
- //. 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} or {\tt DwAddressList}.
-
- virtual ~DwGroup();
-
- const DwGroup& operator = (const DwGroup& aGroup);
- //. This is the assignment operator, which performs a deep copy of
- //. {\tt aGroup}. The parent node of the {\tt DwGroup} object
- //. is not changed.
-
- virtual void Parse();
- //. This virtual function, inherited from {\tt DwMessageComponent},
- //. executes the parse method for {\tt DwGroup} objects. The parse
- //. method creates or updates the broken-down representation from the
- //. string representation. For {\tt DwGroup} objects, the parse method
- //. parses the string representation to extract the group name and to
- //. create a {\tt DwMailboxList} object from the list of mailboxes. This
- //. member function also calls the {\tt Parse()} member function of
- //. the {\tt DwMailboxList} object it creates.
- //.
- //. You should call this member function after you set or modify the
- //. string representation, and before you access the group name or the
- //. mailbox list.
- //.
- //. This function clears the is-modified flag.
-
- virtual void Assemble();
- //. This virtual function, inherited from {\tt DwMessageComponent},
- //. executes the assemble method for {\tt DwGroup} objects. The
- //. assemble method creates or updates the string representation from
- //. the broken-down representation. That is, the assemble method
- //. builds the string representation from its group name and mailbox
- //. list. Before it builds the string representation, this function
- //. calls the {\tt Assemble()} member function of its contained
- //. {\tt DwMailboxList} object.
- //.
- //. You should call this member function after you set or modify either
- //. the group name or the contained {\tt DwMailboxList} object, 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 DwGroup} on the free store that has the same
- //. value as this {\tt DwGroup} object. The basic idea is that of
- //. a virtual copy constructor.
-

-

- //. Sets the name of the phrase part of a group as described in RFC-822.
- //. The phrase is the same as the group name.
-

- //. Provides access to the list of mailboxes that is part of a group as
- //. described in RFC-822.
-
- static DwGroup* NewGroup(const DwString& aStr,
- DwMessageComponent* aParent);
- //. Creates a new {\tt DwGroup} object on the free store.
- //. If the static data member {\tt sNewGroup} is {\tt NULL},
- //. this member function will create a new {\tt DwGroup}
- //. and return it. Otherwise, {\tt NewGroup()} will call
- //. the user-supplied function pointed to by {\tt sNewGroup},
- //. which is assumed to return an object from a class derived from
- //. {\tt DwGroup}, and return that object.
