Advanced Annotation Processing with JSR 269

Descripcion del Video
Forget about runtime annotations as used by Java EE 5 or Spring. Their power cannot be compared to advanced compile-time annotations processed by JavaC during compilation. Annotations of this kind change the way we think about Java. They can improve the scalability, performance, and simplicity of our APIs without the hassle of on-startup processing so common in the EE space these days. In this session, you'll learn how to design an internal declarative DSL in Java, improve the scalability of modular applications, lower startup time, mimic the flexibility of "anything on rails" in plain Java, or simplify your internationalization practices. Learn from Oracle's rich experience with building APIs around annotation processors. Attend the session to understand the power of modern Java. Copyright © 2013 Oracle and/or its affiliates.

Annotations and Annotation Processing: What's New in JDK 8?

Descripcion del Video
JDK 8 will include new features for annotations and annotation processing. This session demonstrates these new features, focusing on repeated annotations and the new core reflection-based implementation of the javax.lang.model. Support for repeated annotations is being included in JDK 8. This will enable you to write code annotated with multiple instances of the same annotation type. Attend this session to see how this can help you write simpler, cleaner code. JDK 8 will provide a new reflection-based back end to the javax.lang.model. This will give you access to a unified, mirror-based, easy-to-use introspection API for a runtime-based view of your code. Learn how to use this new back end for runtime processing of code, including annotations. Copyright © 2013 Oracle and/or its affiliates.

Advanced Topics in Programming Languages: JSR-305: Java annotations For Defects

Descripcion del Video
Google Tech Talks August 8, 2007 ABSTRACT Advanced Topics in Programming Languages: JSR-305: Java annotations for software defect detection This talk will describe the current status of JSR-305, Java annotations for software defect detection. This JSR will define several standard Java annotations for properties such as @Nonnegative and @Nonnull that can be used to document your design intentions in a way that be interpreted by multiple software tools (such as FindBugs and IntelliJ). In addition, the talk (and JSR) will discuss the need for inherited and default JSR-305 annotations and propose a way to provide them. We'll also discuss our proposal to define meta-annotations, that allow anyone to define their own annotations (perhaps with associated validators) that will be treated as type qualifiers. For example, far too many old APIs use int's or String's where enums would have been a better choice. By defining a new type qualifier annotation, and annotating both the public static final fields that define the legal values and the parameters that require them, you can enforce a requirement that only the static fields are used to provide values to the parameters.
