BasicScanner

public abstract class AbstractScanner
extends java.lang.Object

Classpath scanner adapted from Seam. Finds a 'tag' resource in the classpath and then scans through all the directories and files inside the JAR or directory where the tag resource was found. This can be used to iterate through all the classes in a particular class path element to find all classes that implement a particular interface, for example.
