This tool assumes that * annotation handlers will be registered to it to process a particular annotation * type. These annotation handlers have no particular knowledge outside of the * annotation they process and the annoted element on which the annotation was * defined. * </p> * <p> * The AnnotationProcessor tool implementation is responsible for maintening a * list of annotations handlers per annotation type. AnnotationHandler are added * to the tool through the pushAnnotationHandler and can be removed through the * popAnnotationHandler. Alternatively, the Factory singleton can be used to get * an initialized AnnotationProcessor with all the default AnnotationHandler. * </p> * <p> * The tool uses the ProcessingContext to have access to Class instances. Each * class instance will be processed in order, and if annotations are present, the * tool will also process Field, Constructor and Methods elements. Each time the * annotation processor switches for one particular AnnotatedElement to another, * it will send start and stop events to any AnnotatedElementHandler interface * implementation registered within the ProcessingContext. This allow client * code to keep context information about the AnnotatedElements being * processed since AnnotationHandler only know about the AnnotatedElement the * annotation was defined on. * </p> * @since 9.0 * @auther Jerome Dochez */ package org.glassfish.apf;
