Examples of org.jboss.aop.metadata.DynamicSimpleClassMetadataLoader

org.jboss.aop.metadata.DynamicSimpleClassMetadataLoader
An extension of SimpleClassMetadataLoader, allowing us to add metadata without resorting to XML. Intention is for dynamically adding metadata at runtime @author Kabir Khan @version $Revision$
