<DL>
<DD>Return an input stream for this part's "content". Any
mail-specific transfer encodings will be decoded before the
input stream is provided. <p>
This is typically a convenience method that just invokes
the DataHandler's <code>getInputStream()</code> method.<DD><DL>

public java.lang.Object <B>getContent</B>()
throws java.io.IOException,
<A HREF="../../javax/mail/MessagingException.html">MessagingException</A></PRE>
<DL>
<DD>Return the content as a Java object. The type of the returned
object is of course dependent on the content itself. For example,
the object returned for "text/plain" content is usually a String
object. The object returned for a "multipart" content is always a
Multipart subclass. For content-types that are unknown to the
DataHandler system, an input stream is returned as the content <p>
This is a convenience method that just invokes the DataHandler's
getContent() method<DD><DL>

<DD>This method provides the mechanism to set this part's content.
The DataHandler wraps around the actual content.<DD><DL>

public void <B>setContent</B>(java.lang.Object obj,

throws <A HREF="../../javax/mail/MessagingException.html">MessagingException</A></PRE>
<DL>
<DD>A convenience method for setting this part's content. The part
internally wraps the content in a DataHandler. <p>
Note that a DataContentHandler class for the specified type should
be available to the JavaMail implementation for this to work right.
i.e., to do <code>setContent(foobar, "application/x-foobar")</code>,
a DataContentHandler for "application/x-foobar" should be installed.
Refer to the Java Activation Framework for more information.<DD><DL>

the appropriate encoding algorithm to be used. <p>
The bytestream is typically used for sending.<DD><DL>
