</PRE>

A dependency analyzer analyzes dependencies between Java classes to
 determine the minimal set of classes which are required by a set of
 &quot;root&quot; classes. Different implementations of this interface can
 use different strategies and libraries to determine the required set. For
 example, some analyzers will use class files while others might use
 source files. Analyzer specific configuration is catered for through a
 generic configure method
