In MIME++, {\tt DwAddressList} is a container for objects +//. of type {\tt DwAddress}, and it contains various member functions +//. to manage its contained objects. {\tt DwAddressList} is also a +//. {\tt DwFieldBody}. This reflects the fact that certain RFC-822 header +//. fields, such as the ``To'' header field, have a list of addresses +//. as their field bodies. +//============================================================================= +// Last modified 1997-08-23 +//+ Noentry ~DwAddressList sClassName CopyList _PrintDebugInfo + + +class DW_EXPORT DwAddressList : public DwFieldBody { + +public: + + DwAddressList(); + DwAddressList(const DwAddressList& aList); + DwAddressList(const DwString& aStr, DwMessageComponent* aParent=0); + //. The first constructor is the default constructor, which sets the + //. {\tt DwAddressList} object's string representation to the empty string + //. and sets its parent to {\tt NULL}. + //. + //. The second constructor is the copy constructor, which copies the + //. string representation and all {\tt DwAddress} objects from {\tt aList}. + //. The parent of the new {\tt DwAddressList} object is set to {\tt NULL}. + //. + //. The third constructor copies {\tt aStr} to the {\tt DwAddressList} + //. 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 ~DwAddressList(); + + const DwAddressList& operator = (const DwAddressList& aList); + //.

This virtual function, inherited from {\tt DwMessageComponent}, + //. executes the parse method for {\tt DwAddressList} objects. The parse + //. method creates or updates the broken-down representation from the + //. string representation. For {\tt DwAddressList} objects, the parse + //. method parses the string representation to create a list of + //. {\tt DwAddress} objects. This member function also calls the + //. {\tt Parse()} member function of each {\tt DwAddress} object in + //. its list. + //. + //. You should call this member function after you set or modify the + //. string representation, and before you access any of the contained + //. {\tt DwAddress} objects. + //. + //. This function clears the is-modified flag. + + virtual void Assemble(); + //. This virtual function, inherited from {\tt DwMessageComponent}, + //. executes the assemble method for {\tt DwAddressList} 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 list of {\tt DwAddress} + //. objects. Before it builds the string representation for the + //. {\tt DwAddressList} object, this function first calls the + //. {\tt Assemble()} member function of each {\tt DwAddress} object + //. in its list. + //. + //.
