Standard JMF class -- see
this class in the JMF Javadoc.
This class is used to locate DataSource and MediaHandler classes.
For example, if "org.foo" is in the protocolPrefixList, when searching for a
DataSource for a particular protocol "fooproto", it will look for
org.foo.media.protocol.fooproto.DataSource.
For example, if "org.foo" is in the contentPrefixList, when searching for
a MediaHandler for a particular content "video.foovid", it will look for
org.foo.media.content.video.foovid.Handler.
This class does not actually do the searching for these classes, it only
provides the list. The prefixes are to be searched in order until
a suitable class is found.
