Custom plug-in types can also be registered. The predefined plug-in types are: <ul> <li>DEMULTIPLEXER = 1<BR></li> <li>CODEC = 2<BR></li> <li>EFFECT = 3<BR></li> <li>RENDERER = 4<BR></li> <li>MULTIPLEXER = 5<BR></li> </ul> <p> This <CODE>PlugInManager</CODE> is a wrapper for the actual implementation, which it expects to find in <CODE>javax.media.pim.PlugInManager</CODE>. If this implementation exists and is an instance of <CODE>javax.media.PlugInManager</CODE>, all calls to <CODE>javax.media.PlugInManager</CODE> are redirected to <CODE>javax.media.pim.PlugInManager</CODE>. If the implementation is not found, all calls to <CODE>javax.media.PlugInManager</CODE> methods will fail and return null or invalid data.<P><DL><DT><B>Since: </B><DD>JMF 2.0</DD></DL><HR><P><!--
