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 ...

TypegetType() Returns the underlying type that this annotated type represents. Methods inherited from interface java.lang.reflect.AnnotatedElement getAnnotation,getAnnotations,getAnnotationsByType,getDeclaredAnnotation,getDeclaredAnnotations,getDeclaredAnnotationsByType,isAnnotationPresent ...
eAnnotations =扩展的元数据EAnnotation 如果元素的类型是预定义的模式类型之一,则将对应EAttribute的eType设置为对应的从XMLType模型创建的EDataType(参见第9.9节)。如果元素有用户定义的简单类型,则将eType设置为从简单类型创建的EDataType,如第9.2节所述。 否则,如果元素声明映射到EReference,eType则被设置为对应...

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....
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...
