A package prefix specifies the prefix for a complete class name. A factory uses a package-prefix list to find a class that might belong to any of the packages that are referenced in the prefix list.<p> The <code>Manager</code> uses package-prefix lists to find protocol handlers and content handlers for time-based media.<p> The current version of a package-prefix list is obtained with the <code>get<package-prefix>List</code> method. This method returns the prefix list in use; any changes to the list take effect immediately. Unless it is made persistent with <code>commit<package-prefix>List</code>, a package-prefix list is only valid while the <code>Manager</code> is referenced. The <code>commit<package-prefix>List</code> method ensures that any changes made to a package-prefix list are still visible the next time that the <code>Manager</code> is referenced.<P><DL><DT><B>See Also: </B><DD><A HREF="../../javax/media/Manager.html"><CODE>Manager</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#PackageManager()">PackageManager</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><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>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#commitContentPrefixList()">commitContentPrefixList</A></B>()</CODE><BR> Make changes to the content prefix-list persistent.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#commitProtocolPrefixList()">commitProtocolPrefixList</A></B>()</CODE><BR> Make changes to the protocol package-prefix list persistent.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.util.Vector</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#getContentPrefixList()">getContentPrefixList</A></B>()</CODE><BR> Get the current value of the content package-prefix list.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.util.Vector</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#getProtocolPrefixList()">getProtocolPrefixList</A></B>()</CODE><BR> Get the current value of the protocol package-prefix list.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#setContentPrefixList(java.util.Vector)">setContentPrefixList</A></B>(java.util.Vector list)</CODE><BR> Set the current value of the content package-prefix list.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/media/PackageManager.html#setProtocolPrefixList(java.util.Vector)">setProtocolPrefixList</A></B>(java.util.Vector list)</CODE><BR> Set the protocol package-prefix list.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.lang.Object</B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait</CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><A NAME="constructor_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Constructor Detail</B></FONT></TD></TR></TABLE><A NAME="PackageManager()"><!-- --></A><H3>PackageManager</H3><PRE>public <B>PackageManager</B>()</PRE><DL></DL><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="getProtocolPrefixList()"><!-- --></A><H3>getProtocolPrefixList</H3><PRE>public static java.util.Vector <B>getProtocolPrefixList</B>()</PRE><DL><DD>Get the current value of the protocol package-prefix list. <p><DD><DL><DT><B>Returns:</B><DD>The protocol package-prefix list.</DL></DD></DL><HR><A NAME="setProtocolPrefixList(java.util.Vector)"><!-- --></A><H3>setProtocolPrefixList</H3><PRE>public static void <B>setProtocolPrefixList</B>(java.util.Vector list)</PRE><DL><DD>Set the protocol package-prefix list.
