AnnotationReader

public class AnnotationReader (Code)

Reads Java 5 java.lang.annotation.RetentionPolicy.RUNTIME and java.lang.annotation.RetentionPolicy.CLASS annotations from the class' bytecode.

Can be used with a custom implementation of the org.codehaus.backport175.reader.bytecode.spi.BytecodeProvider interface.

Note: does not handles java.lang.annotation.Inherited feature. This has to be done in the higher level that knows about the class hierarchy (see backport175.Annotations f.e)
