Class AnnotationDB
java.lang.Object
org.java.plugin.extension.annotations.scanner.AnnotationDB
- All Implemented Interfaces:
- java.io.Serializable
public class AnnotationDB
- extends java.lang.Object
- implements java.io.Serializable
The class allows you to scan an arbitrary set of "archives" for .class files. These class files
are parsed to see what annotations they use. Two indexes are created.
One is a map of annotations and what classes
use those annotations. This could be used, for example, by an EJB deployer to find all the EJBs contained
in the archive
Another is a mpa of classes and what annotations those classes use.
