<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 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.

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>.

This is the assignment operator, which performs a deep copy of

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.

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.
