Annotations have been introduced from Java 5.0 (JSR-175).Java 6 has introduced a new JSR called JSR-269, which is the Pluggable Annotation Processing API.
I am trying to learn about Pluggable Annotation but unable to get it properly,so asking in SO.
- What Pluggable Annotation is actually ?
- How it is different from Annotations and what are the extra features Pluggable Annotation (JSR-269) provides over Annotations (JSR-175)
- I am looking for a way to take advantages of Pluggable Annotation, how can I achieve that? (practical scenario).
It's not the annotations that are "pluggable", but rather the entire processing API. Nothing changed about annotations; just the way they are processed. If you read the JSR-269 outline, it makes this clear: "this JSR will define APIs to allow annotation processors to be created using a standard pluggable API."
