<A NAME="MimeMultipart()"><!-- --></A><H3>
MimeMultipart</H3>
<PRE>
public <B>MimeMultipart</B>()</PRE>
<DL>
<DD>Default constructor. An empty MimeMultipart object
 is created. Its content type is set to "multipart/mixed".
 A unique boundary string is generated and this string is
 setup as the "boundary" parameter for the 
 <code>contentType</code> field. <p>

 MimeBodyParts may be added later.</DL>
<HR>

<A NAME="MimeMultipart(java.lang.String)"><!-- --></A><H3>
MimeMultipart</H3>
<PRE>
public <B>MimeMultipart</B>(java.lang.String&nbsp;subtype)</PRE>
<DL>
<DD>Construct a MimeMultipart object of the given subtype.
 A unique boundary string is generated and this string is
 setup as the "boundary" parameter for the 
 <code>contentType</code> field. <p>

 MimeBodyParts may be added later.</DL>
<HR>

<A NAME="MimeMultipart(javax.activation.DataSource)"><!-- --></A><H3>
MimeMultipart</H3>
<PRE>
public <B>MimeMultipart</B>(javax.activation.DataSource&nbsp;ds)
              throws <A HREF="../../../javax/mail/MessagingException.html">MessagingException</A></PRE>
<DL>
<DD>Constructs a MimeMultipart object and its bodyparts from the 
 given DataSource. <p>

 This constructor handles as a special case the situation where the
 given DataSource is a MultipartDataSource object.  In this case, this
 method just invokes the superclass (i.e., Multipart) constructor
 that takes a MultipartDataSource object. <p>

 Otherwise, the DataSource is assumed to provide a MIME multipart 
 byte stream.  The parser extracts the "boundary" parameter from the
 content type of this DataSource, skips the 'preamble' and reads
 bytes till the terminating boundary and creates MimeBodyParts 
 for each part of the stream.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>ds</CODE> - DataSource, can be a MultipartDataSource</DL>

                      throws <A HREF="../../../javax/mail/MessagingException.html">MessagingException</A></PRE>
<DL>
<DD>Update headers. The default implementation here just
 calls the <code>updateHeaders</code> method on each of its
 children BodyParts. <p>

 Note that the boundary parameter is already set up when
 a new and empty MimeMultipart object is created. <p>

 This method is called when the <code>saveChanges</code>
 method is invoked on the Message object containing this
 Multipart. This is typically done as part of the Message
 send process, however note that a client is free to call
 it any number of times. So if the header updating process is 
 expensive for a specific MimeMultipart subclass, then it
 might itself want to track whether its internal state actually
 did change, and do the header updating only if necessary.</DL>
