org.apache.felix.scrplugin.description.ClassDescription
A ClassDescription is describing the found annotations of a class. Its basically used as a wrapper to hold all the various annotations found in a class. This description only contains the annotations found in the current class, but not in any superclass. The annotations are available as descriptions. @see ComponentDescription @see ServiceDescription @see ReferenceDescription @see PropertyDescription
