Through <code>DataContentHandlers</code> the framework can be extended to convert streams in to objects, and to write objects to streams. <p> Applications don't generally call the methods in DataContentHandlers directly. Instead, an application calls the equivalent methods in DataHandler. The DataHandler will attempt to find an appropriate DataContentHandler that corresponds to its MIME type using the current DataContentHandlerFactory. The DataHandler then calls through to the methods in the DataContentHandler.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/activation/DataContentHandler.html#getContent(javax.activation.DataSource)">getContent</A></B>(<A HREF="../../javax/activation/DataSource.html" title="interface in javax.activation">DataSource</A> ds)</CODE><BR> Return an object representing the data in its most preferred form. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/activation/DataContentHandler.html#getTransferData(java.awt.datatransfer.DataFlavor, javax.activation.DataSource)">getTransferData</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/datatransfer/DataFlavor.html" title="class or interface in java.awt.datatransfer">DataFlavor</A> df, <A HREF="../../javax/activation/DataSource.html" title="interface in javax.activation">DataSource</A> ds)</CODE><BR> Returns an object which represents the data to be transferred. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/datatransfer/DataFlavor.html" title="class or interface in java.awt.datatransfer">DataFlavor</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/activation/DataContentHandler.html#getTransferDataFlavors()">getTransferDataFlavors</A></B>()</CODE><BR> Returns an array of DataFlavor objects indicating the flavors the data can be provided in. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/activation/DataContentHandler.html#writeTo(java.lang.Object, java.lang.String, java.io.OutputStream)">writeTo</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A> obj, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> mimeType, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/io/OutputStream.html" title="class or interface in java.io">OutputStream</A> os)</CODE><BR>⌨️ 快捷键说明
