scala.reflect.internal.AnnotationInfos.AnnotationInfo

Typed information about an annotation. It can be attached to either a symbol or an annotated type.

Annotations are written to the classfile as Java annotations if atp conforms to ClassfileAnnotation (the classfile parser adds this interface to any Java annotation class).

Annotations are pickled (written to scala symtab attribute in the classfile) if atp inherits form StaticAnnotation.

args stores arguments to Scala annotations, represented as typed trees. Note that these trees are not transformed by any phases following the type-checker.

assocs stores arguments to classfile annotations as name-value pairs.
