It is an abstract base class that defines the +interface common to all structured field bodies. +<P> +In the tree (broken-down) representation of a message, a +<B><TT>DwFieldBody</TT></B> object may be either a leaf node, having a parent +but no child nodes, or an intermediate node, having a parent and one or more +child nodes. The parent node is the +<B><TT><A HREF="field.html">DwField</A></TT></B> object that contains it. +Child nodes, if present, depend on the particular subclass of +<B><TT>DwFieldBody</TT></B> that is instantiated. A +<B><TT>DwAddressList</TT></B> object, for example, has +<B><TT>DwAddress</TT></B> objects as its child nodes. +<P> +Since <B><TT>DwFieldBody</TT></B> is an abstract base class, you cannot create +instances of it directly. Normally, objects of classes derived from +<B><TT>DwFieldBody</TT></B> are obtained by calling convenience member functions +in the class <B><TT><A HREF="headers.html">DwHeaders</A></TT></B>. +<P> +Some MIME parsers are broken in that they do not handle the folding of some +fields properly. <B><TT>DwFieldBody</TT></B> folds its string representation +by default. You can disable folding, however, by calling the +<B><TT>SetFolding()</TT></B> member function.

The parent of the new +<B><TT>DwFieldBody</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>DwFieldBody</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.

The offset is used when folding +lines.
