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...
In this way, you can build on top of the Java type system, adding specific checks when and where you want them. With the judicious use of type annotations and the presence of pluggable type checkers, you can write code that is stronger and less prone to error. In many cases, you do ...
Models an annotation on a type use, as defined in 4.7.19 and 4.7.20.Since: 22 See Also: RuntimeVisibleTypeAnnotationsAttributePREVIEW RuntimeInvisibleTypeAnnotationsAttributePREVIEWNested Class Summary Nested Classes Modifier and Type Interface Description static interface TypeAnnotation.CatchTarget...
We report here our recent progress in extending an Eclipse plug-in to use programmer supplied documentation of database access in the form of type annotations for providing a visual map of interactions between Java code and relational databases. A primary motivation is to facilitate code maintenance...
If java annotation value is array type, it will make getAnnotationsByType throw class cast issue, it seems that in java we can declare a single value for annotation value whose type is array, like this one @Retention(CLASS) public @interface JavaAnnotationWithList { Class[] testList(); }...

The platform defines a small number of basic annotations in java.lang. The original set were @Override, @Deprecated, and @SuppressWarnings—which were used to indicate that a method was overriden, deprecated, or that it generated some compiler warnings that should be suppressed. These were augmen...
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....
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...
