public interface AnnotationRemapper

Allows remapping of annotations from one annotation set to another at compilation time. Similar to the AnnotationMapper interface with the following differences:

• Can be applied to a whole package of annotations.
• The original annotation being mapped is not retained in the metadata.

Useful for supporting multiple annotation sets that reside in different package namespaces, however are largely similar in function, for example javax.annotation.Nullable and io.micronaut.core.annotation.Nullable. One can remap these to a single annotation internally at compilation time.

Since:

1.2.0
