Examples of org.apache.xbean.finder.AnnotationFinder

org.apache.xbean.finder.AnnotationFinder
ClassFinder searches the classpath of the specified classloader for packages, classes, constructors, methods, or fields with specific annotations.
For security reasons ASM is used to find the annotations. Classes are not loaded unless they match the requirements of a called findAnnotated* method. Once loaded, these classes are cached. @version $Rev: 1326452 $ $Date: 2012-04-15 17:24:14 -0700 (Sun, 15 Apr 2012) $
