JSR 308, Annotations on Java Types, has been incorporated as part of Java SE 8. This JSR builds upon the existing annotation framework, allowing type annotations to become part of the language. Beginning in Java SE 8, annotations can be applied to types in addition to all of their existing...

Annotations, a form of metadata, provides data about a program that is not part of the program itself. Annotations have no direct effect on the operation of the code they annotate. Annotations have a number of uses, among them: Information for the compiler Compile-time and deployment-time pro...

Note that any annotations returned by methods on this interface are type annotations (JLS 9.7.4) as the entity being potentially annotated is a type.See Java Language Specification: 4.1 The Kinds of Types and Values4.2 Primitive Types and Values4.3 Reference Types and Values4.4 Type Variables4.5...
In my previous article in this series, I introduced Java's new metadata facility and described the built-in annotation types @Override,@Deprecated, and @SuppressWarnings. In this article I'll show you how to write your own annotation types and make use of the built-in annotations from the ...

The string literal "rawtypes" is used to initialize the annotation element value, and its value can be extracted from the annotation by means of the getValue predicate. We could then write this query to find all @SuppressWarnings annotations attached to constructors, and return both the ...
