25  * Provides the classes necessary to process J2SE 1.5 annotations in the context
26  * of the J2EE application server.
27  *
28  * <p>
29  * Annotations are defined by their annotation type. This tool assumes that
30  * annotation handlers will be registered to it to process a particular annotation
31  * type. These annotation handlers have no particular knowledge outside of the
32  * annotation they process and the annoted element on which the annotation was
33  * defined.
34  * </p>
35  * <p>
36  * The AnnotationProcessor tool implementation is responsible for maintening a
37  * list of annotations handlers per annotation type. AnnotationHandler are added
38  * to the tool through the pushAnnotationHandler and can be removed through the
39  * popAnnotationHandler. Alternatively, the Factory singleton can be used to get
40  * an initialized AnnotationProcessor with all the default AnnotationHandler.
41  * </p>
42  * <p>
43  * The tool uses the ProcessingContext to have access to Class instances. Each
44  * class instance will be processed in order, and if annotations are present, the
45  * tool will also process Field, Constructor and Methods elements. Each time the
46  * annotation processor switches for one particular AnnotatedElement to another,
47  * it will send start and stop events to any AnnotatedElementHandler interface
48  * implementation registered within the ProcessingContext. This allow client
49  * code to keep context information about the AnnotatedElements being
50  * processed since AnnotationHandler only know about the AnnotatedElement the
51  * annotation was defined on.
52  * </p>
