<DL>
<DD>Scans for factory plug-ins on the application class path. This method is
 needed because the application class path can theoretically change, or
 additional plug-ins may become available. Rather than re-scanning the
 classpath on every invocation of the API, the class path is scanned
 automatically only on the first invocation. Clients can call this method
 to prompt a re-scan. Thus this method need only be invoked by
 sophisticated applications which dynamically make new plug-ins available
 at runtime.

 It can be used toget basic information about all the available

 implemented plugins but returns only the availaible one.

 A plugin could be implemented but not availaible due to missing
 dependencies.

 implementation to <A HREF="../../../../../org/geotools/data/coverage/grid/AbstractGridFormat.html" title="class in org.geotools.data.coverage.grid"><CODE>AbstractGridFormat</CODE></A> because the original
