Package eu.bandm.tools.util.classes

Class AnnotationVisitor<D>

java.lang.Object

eu.bandm.tools.util.classes.ClassFileVisitor<D>

eu.bandm.tools.util.classes.AnnotationVisitor<D>

All Implemented Interfaces:

Runnable

public class AnnotationVisitor<D>
extends ClassFileVisitor<D>

Visits the bytecode of a class and collects annotations. The callback method for error handling must be overridden by the user, see superclass documentation.

Warning: not all aspects of annotations are implemented.
