Type Annotations and Pluggable Type SystemsBefore the Java SE 8 release, annotations could only be applied to declarations. As of the Java SE 8 release, annotations can also be applied to any type use. This means that annotations can be used anywhere you use a type. A few examples of ...

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...

java annotations 必填 java anytype 9.5 元素声明 每个模式元素声明映射到EClass中的EAttribute或者EReference,该EClass对应于包含该元素的复杂类型定义;如果属性是全局的,则对应于"DocumentRoot" EClass中的EAttribute或者EReference。 如果其类型简单,元素声明将映射到EAttribute(除了第9.3.5节介绍的特殊情况之外)。
I would like to use the @NotNull and @Nullable annotations on types, as was introduced with java 8. I understood that IDEA 13.1 supports java 8, and therefore also type annotations. I've set up my project to use language level 8.0, and I've added the annotations.jar (from <IDEA>...
静态类型的语言,比如在写 Java 的时候,如果你把一个 int 赋值给了 string 的变量,IDE 会通过类型检查器立即报错并告诉你,你这个值赋值错啦。这个就是 Java 程序的检查阶段。 动态类型的语言,比如在写 Python 的时候,如果不用一些额外的手段,这种低级的错误,并不会在检查时爆出来,只会在运行时爆出来。如果线...
Both compile-time and load-time processing are outside the scope of the annotations proposal, but are presented here as an example of how annotations on types might be used. The processors described here do not require any further changes to Java beyond those described in the \\Type ...

Thrown to indicate that a program has attempted to access an element of an annotation whose type has changed after the annotation was compiled (or serialized). This exception can be thrown by the java.lang.reflect.AnnotatedElement API used to read annotations reflectively....
