This field body specifies the kind +of data contained in the body of a message or a body part. A media type is +described by two keywords: a primary type (or just <I>type</I>) and a +<I>subtype</I>. RFC-2046 specifies the seven primary types text, multipart, +message, image, audio, video, and application. RFC-2077 adds the new primary +type model. +<P> +<B><TT>DwMediaType</TT></B> has member functions that allow you to set or +get the type and subtype as either enumerated values or as strings. It also +contains a list of +<B><TT><A HREF="param.html">DwParameter</A></TT></B> objects that represent +the parameters of the field body. You can use convenience functions to directly +access the boundary parameter of a multipart media type, or to access the +name parameter that is often used with several media types, such as +application/octet-stream. +<P> +Some MIME parsers have problems with folded header fields, and this especially +seems to be a problem with the Content-Type field. To disable folding when +the <B><TT>DwMediaType</TT></B> object is assembled, call the inherited member +function <B><TT>DwFieldBody::SetFolding()</TT></B> with an argument of +<B><TT>DwFalse</TT></B>. +<H2> + <FONT COLOR="navy"> Public Member Functions </FONT> +</H2> +<P> +<FONT COLOR="teal"><B> <A NAME="DwMediaType">DwMediaType</A>() <BR> +DwMediaType(const DwMediaType& aMediaType) <BR> +DwMediaType(const DwString& aStr, DwMessageComponent* aParent=0) +</B></FONT> +<P> +The first constructor is the default constructor, which sets the +<B><TT>DwMediaType</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 performs deep copy +of <B><TT>aMediaType</TT></B>.
