In MIME++, <B><TT>DwAddressList</TT></B> is a container for objects of type <B><TT><A HREF="address.html">DwAddress</A></TT></B>, and it contains various member functions to manage its contained objects. <B><TT>DwAddressList</TT></B> is also a <B><TT><A HREF="fieldbdy.html">DwFieldBody</A></TT></B>. 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. <H2> <FONT COLOR="navy"> Public Member Functions </FONT> </H2> <P> <FONT COLOR="teal"><B> <A NAME="DwAddressList">DwAddressList</A>() <BR> DwAddressList(const DwAddressList& aList) <BR> DwAddressList(const DwString& aStr, DwMessageComponent* aParent=0) </B></FONT> <P> The first constructor is the default constructor, which sets the <B><TT>DwAddressList</TT></B> object's string representation to the empty string and sets its parent to <B><TT>NULL</TT></B>. <P> The second constructor is the copy constructor, which copies the string representation and all <B><TT>DwAddress</TT></B> objects from <B><TT>aList</TT></B>. The parent of the new <B><TT>DwAddressList</TT></B> object is set to <B><TT>NULL</TT></B>. <P> The third constructor copies <B><TT>aStr</TT></B> to the <B><TT>DwAddressList</TT></B> object's string representation and sets <B><TT>aParent</TT></B> as its parent. The virtual member function <B><TT>Parse()</TT></B> should be called immediately after this constructor in order to parse the string representation. Unless it is <B><TT>NULL</TT></B>, <B><TT>aParent</TT></B> should point to an object of a class derived from <B><TT>DwField</TT></B>. <P> <FONT COLOR="teal"><B> const DwAddressList& <A NAME="op_eq">operator =</A> (const DwAddressList& aList) </B></FONT> <P> This is the assignment operator, which performs a deep copy of <B><TT>aList</TT></B>. The parent node of the <B><TT>DwAddressList</TT></B> object is not changed. <P> <FONT COLOR="teal"><B> virtual void <A NAME="Parse">Parse</A>() </B></FONT> <P> This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>, executes the parse method for <B><TT>DwAddressList</TT></B> objects. The parse method creates or updates the broken-down representation from the string representation. For <B><TT>DwAddressList</TT></B> objects, the parse method parses the string representation to create a list of <B><TT>DwAddress</TT></B> objects. This member function also calls the <B><TT>Parse()</TT></B> member function of each <B><TT>DwAddress</TT></B> object in its list. <P> You should call this member function after you set or modify the string representation, and before you access any of the contained <B><TT>DwAddress</TT></B> objects. <P> This function clears the is-modified flag. <P> <FONT COLOR="teal"><B> virtual void <A NAME="Assemble">Assemble</A>() </B></FONT> <P> This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>, executes the assemble method for <B><TT>DwAddressList</TT></B> 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 <B><TT>DwAddress</TT></B> objects. Before it builds the string representation for the <B><TT>DwAddressList</TT></B> object, this function first calls the <B><TT>Assemble()</TT></B> member function of each <B><TT>DwAddress</TT></B> object in its list. <P> You should call this member function after you set or modify any of the contained <B><TT>DwAddress</TT></B> objects, and before you retrieve the string representation. <P> This function clears the is-modified flag. <P> <FONT COLOR="teal"><B> virtual DwMessageComponent* <A NAME="Clone">Clone</A>() const </B></FONT> <P> This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>, creates a new <B><TT>DwAddressList</TT></B> on the free store that has the same value as this <B><TT>DwAddressList</TT></B> object. The basic idea is that of a virtual copy constructor. <P> <FONT COLOR="teal"><B> DwAddress* <A NAME="FirstAddress">FirstAddress</A>() const </B></FONT> <P> Gets the first <B><TT>DwAddress</TT></B> object in the list. Use the member function <B><TT>DwAddress::Next()</TT></B> to iterate. Returns <B><TT>NULL</TT></B> if the list is empty. <P> <FONT COLOR="teal"><B> void <A NAME="Add">Add</A>(DwAddress* aAddr) </B></FONT> <P> Adds <B><TT>aAddr</TT></B> to the end of the list of <B><TT>DwAddress</TT></B> objects maintained by this <B><TT>DwAddressList</TT></B> object. <P> <FONT COLOR="teal"><B> void <A NAME="Remove">Remove</A>(DwAddress* aAddr) </B></FONT> <P> Removes <B><TT>aAddr</TT></B> from the list of <B><TT>DwAddress</TT></B> objects maintained by this <B><TT>DwAddressList</TT></B> object. The <B><TT>DwAddress</TT></B> object is not deleted by this member function. <P> <FONT COLOR="teal"><B> void <A NAME="DeleteAll">DeleteAll</A>() </B></FONT> <P> Removes and deletes all <B><TT>DwAddress</TT></B> objects from the list maintained by this <B><TT>DwAddressList</TT></B> object. <P> <FONT COLOR="teal"><B> static DwAddressList* <A NAME="NewAddressList">NewAddressList</A>(const DwString& aStr, DwMessageComponent* aParent) </B></FONT> <P> Creates a new <B><TT>DwAddressList</TT></B> object on the free store. If the static data member <B><TT>sNewAddressList</TT></B> is <B><TT>NULL</TT></B>, this member function will create a new <B><TT>DwAddressList</TT></B> and return it. Otherwise, <B><TT>NewAddressList()</TT></B> will call the user-supplied function pointed to by <B><TT>sNewAddressList</TT></B>, which is assumed to return an object from a class derived from <B><TT>DwAddressList</TT></B>, and return that object. <P> <FONT COLOR="teal"><B> virtual void <A NAME="PrintDebugInfo">PrintDebugInfo</A>(ostream& aStrm, int aDepth=0) const </B></FONT> <P> This virtual function, inherited from <B><TT>DwMessageComponent</TT></B>, prints debugging information about this object to <B><TT>aStrm</TT></B>. It will also call <B><TT>PrintDebugInfo()</TT></B> for any of its child components down to a level of <B><TT>aDepth</TT></B>. <P> This member function is available only in the debug version of the library. <P> <FONT COLOR="teal"><B> virtual void <A NAME="CheckInvariants">CheckInvariants</A>() const </B></FONT> <P> Aborts if one of the invariants of the object fails. Use this member function to track down bugs. <P> This member function is available only in the debug version of the library. <H2> <FONT COLOR="navy"> Public Data Members </FONT> </H2> <P> <FONT COLOR="teal"><B> static DwAddressList* (*<A NAME="sNewAddressList">sNewAddressList</A>)(const DwString&, DwMessageComponent*) </B></FONT> <P> If <B><TT>sNewAddressList</TT></B> is not <B><TT>NULL</TT></B>, it is assumed to point to a user-supplied function that returns a pointer to an object from a class derived from <B><TT>DwAddressList</TT></B>. <H2> <FONT COLOR="navy"> Protected Data Members </FONT> </H2> <P> <FONT COLOR="teal"><B> DwAddress* <A NAME="mFirstAddress">mFirstAddress</A> </B></FONT> <P> Points to first <B><TT>DwMailbox</TT></B> object in list. <P> </BODY></HTML>
