public class GetClassListService
extends Service

This service finds the classes that implement or extend a given base class. The SearchClass argument specifies the name of the class to search for implementors of, and the service searches its own classpath (i.e. the classpath of the instance of the service) for implementors which are returned as a collection of class names.

By default the search covers only the com.ail package tree. However, the SearchPackage argument may be used to specify an alternate package tree to search.

An empty list is returned if the class being searched for does not exist.
