# Annotation Interface Retention

@Documented @Retention(RUNTIME) @Target(ANNOTATION_TYPE) public @interface Retention
Indicates how long annotations with the annotated interface are to be retained. If no Retention annotation is present on an annotation interface declaration, the retention policy defaults to `RetentionPolicy.CLASS`.

A Retention meta-annotation has effect only if the meta-annotated interface is used directly for annotation. It has no effect if the meta-annotated interface is used as a member interface in another annotation interface.
