Java Reflection API Research (2)--java.lang.reflect detailed content and relationship

For the latest java1.8, the structure of the interface in reflect is this:

• Java.lang.reflect. annotatedelement
  • Java.lang.reflect. Annotatedtype
    • Java.lang.reflect. Annotatedarraytype
    • Java.lang.reflect. Annotatedparameterizedtype
    • Java.lang.reflect. annotatedtypevariable
    • Java.lang.reflect. Annotatedwildcardtype
  • Java.lang.reflect. genericdeclaration
  • Java.lang.reflect. typevariable<D> (also extends Java.lang.reflect.Type)
• Java.lang.reflect. Invocationhandler
• Java.lang.reflect. Member
• Java.lang.reflect. Type
• Java.lang.reflect. Genericarraytype
• Java.lang.reflect. Parameterizedtype
• Java.lang.reflect. typevariable<D> (also extends Java.lang.reflect.AnnotatedElement)
• Java.lang.reflect. Wildcardtype

Several sub-interfaces under the Annotatedtype can be used without a tube, and other structures look very simple.

The inheritance structure of the class is as follows:

• Java.lang.reflect. AccessibleObject (Implements Java.lang.reflect.AnnotatedElement)
  • Java.lang.reflect. executable (Implements Java.lang.reflect.GenericDeclaration, Java.lang.reflect.Member)
    • Java.lang.reflect. Constructor<T>
    • Java.lang.reflect. Method
  • Java.lang.reflect. Field (Implements Java.lang.reflect.Member)
• Java.lang.reflect. Array
• Java.lang.reflect. Modifier
• Java.lang.reflect. Parameter (Implements Java.lang.reflect.AnnotatedElement)
• Java.security. Permission (Implements Java.security.Guard, java.io.Serializable)
  • Java.security. basicpermission (Implements Java.io.Serializable)
    • Java.lang.reflect. reflectpermission
• Java.lang.reflect. Proxy (Implements Java.io.Serializable)

Where the security of a few can first ignore

And for Java.lang.reflect.ReflectPermission, his main function is to remove the reflection of the default permission control, allowing direct manipulation of objects such as the private modifier of the property or method, and so on.

Because the default behavior of the reflection mechanism is limited to Java access control, for example, access to private methods, fields, unless you have access to it, Java security allows you to see which fields are available to any object, without allowing them to read their values (read throws an exception). However, if a Java program is not under the control of the security manager, access control can be overridden. To achieve this, you need to invoke the Setaccessible () method of the field, method, constructor object.

The Permission class for the reflection operation. Reflectpermission is a specified permission , no action. The currently defined unique name is suppressaccesschecks, which allows the cancellation of standard Java-language access checks performed by the reflective object on its point of use-for public, default (package) access, protected, Private member.

The inheritance and implementation diagram for this package is as follows:
