If RetentionPolicy of a annotation is Runtime, It should be mapped to below
method in "visible" argument as I know:
This is my modified version and works the way expected. I'm just returning
null when annotation is visible by judging just by looking at visible
argument.
I'm not sure if this "visible" argument is ever sent true when
RetentionPolicy of a annotation is not RetentionPolicy.Runtime.
/**
* Visit class annotations.
* This method detects @component and @provides annotations.
* @param desc : annotation descriptor.
* @param visible : is the annotation visible at runtime.
* @return the annotation visitor.
* @see
org.objectweb.asm.ClassAdapter#visitAnnotation(java.lang.String, boolean)
*/
public AnnotationVisitor visitAnnotation(String desc, boolean visible) {
/*
* Visible annotations are mostly destined to be read by reflection
* at runtime. We retain runtime visible annotations on component
* as they are and left them out in meta-data calculation.
*/
if(visible){
return null;
}
// Return the visitor to be executed (may be null)
return registry.selection(workbench)
.type(node)
.annotatedWith(desc)
.get();
}
