<DL>
<DD>Builds a list of plug-ins that satisfy the specified plug-in type and input and
 output formats. Either or both of the formats can be null. 
 If <code>input</code> is null, <CODE>getPlugInList</CODE>
 returns a list of plug-ins of the specified type that match the output format.  If <code>output</code> is 
 null, <CODE>getPlugInList</CODE> returns a list of plug-ins of the specified type that match the input format.
 If both parameters are null, <CODE>getPlugInList</CODE> returns a list of all of the 
 plug-ins of the specified type.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>input</CODE> - The input <CODE>Format</CODE> to be supported by the plug-in.<DD><CODE>output</CODE> - The output <CODE>Format</CODE> to be generated by the plug-in.<DD><CODE>type</CODE> - The type of plug-in to search for, for example: 
 <CODE>DEMULTIPLEXER</CODE>, <CODE>CODEC</CODE>, <CODE>EFFECT</CODE>, 
 <CODE>MULTIPLEXER</CODE>, or <CODE>RENDERER</CODE>.<DT><B>Returns:</B><DD>A <CODE>Vector</CODE> that contains the plug-in list.</DL>

<DL>
<DD>Sets the search order for the plug-ins of the specified type. This enables
 you to control what plug-in is selected when multiple plug-ins of a particular 
 type support the same input and output formats. (The first match is selected by
 the <CODE>Processor</CODE>.)
 This list is valid
 for the duration of the session only, unless <code>commit</code> is
 called.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>plugins</CODE> - A <CODE>Vector</CODE> that lists the plug-ins in the order that they
 should be searched.<DD><CODE>type</CODE> - The type of plug-in contained in the search list, for example:

<DL>
<DD>Commits any changes made to the plug-in list. 
 The <CODE>commit</CODE> method must be called when a plug-in is added or removed
 to make the change permanent.
 Changes to the search
 order can also be made permanent by calling <CODE>commit</CODE>.</DL>

<DL>
<DD>Registers a new plug-in. This plug-in is automatically appended
 to the list of plug-ins searched when a <CODE>Processor</CODE> is created. 
 Registration will fail if a plug-in of the same name
 already exists. The <code>commit</code> method has to be called to make the
 addition permanent.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>classname</CODE> - A <CODE>String</CODE> that contains the class name of the new plug-in.<DD><CODE>in</CODE> - A <CODE>Format</CODE> array that contains the input formats that the plug-in supports.<DD><CODE>out</CODE> - A <CODE>Format</CODE> array that contains the output formats that the plug-in supports.<DD><CODE>type</CODE> - The type of the new plug-in, for example: 
 <CODE>DEMULTIPLEXER</CODE>, <CODE>CODEC</CODE>, <CODE>EFFECT</CODE>, 
 <CODE>MULTIPLEXER</CODE>, or <CODE>RENDERER</CODE>.<DT><B>Returns:</B><DD><CODE>true</CODE> if the plug-in is registered successfully, <CODE>false</CODE> if it could
