<FONT COLOR="navy"> DESCRIPTION </FONT>
</H2>
<P>
<B><TT>DwAddressList</TT></B> represents a list of <I>addresses</I> as described
in RFC-822. 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 tqcontains
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>
<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>.
