Multipart provides methods to retrieve and set its subparts. <p> Multipart also acts as the base class for the content object returned by most Multipart DataContentHandlers. For example, invoking getContent() on a DataHandler whose source is a "multipart/signed" data source may return an appropriate subclass of Multipart. <p> Some messaging systems provide different subtypes of Multiparts. For example, MIME specifies a set of subtypes that include "alternative", "mixed", "related", "parallel", "signed", etc. <p> Multipart is an abstract class. Subclasses provide actual implementations.<P><P><DL><DT><B>Version:</B></DT> <DD>1.13, 02/03/27</DD><DT><B>Author:</B></DT> <DD>John Mani</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ========
