Constructor getAnnotatedReceiverType() method in Java with Examples (original) (raw)

Last Updated : 25 Nov, 2019

The getAnnotatedReceiverType() method of a Constructor class is used to return an AnnotatedType object that represents the AnnotatedType to specify the receiver type of this constructor. If the constructor has a receiver parameter then The receiver type of a constructor is available. If this constructor either has no receiver parameter or has a receiver parameter with no annotations on its type, then the return value is an AnnotatedType object representing an element with no annotations. If this constructor is a top-level static member then the return value is null.

Syntax:

public AnnotatedType getAnnotatedReceiverType()

Parameters: This method accepts nothing.

Return value: This method returns an object of AnnotatedType representing the receiver type of the method or constructor represented by this Executable or null if this Executable can not have a receiver parameter.

Below programs illustrate the getAnnotatedReceiverType() method:
Program 1:

import java.lang.annotation.ElementType;

import java.lang.annotation.Retention;

import java.lang.annotation.RetentionPolicy;

import java.lang.annotation.Target;

import java.lang.reflect.AnnotatedType;

import java.lang.reflect.Constructor;

public class GFG {

`` public static void main(String[] args)

`` throws NoSuchMethodException

`` {

`` Constructor<?> c = Test. class .getConstructors()[ 0 ];

`` AnnotatedType atr

`` = c.getAnnotatedReceiverType();

`` System.out.println(atr);

`` System.out.println( "Type = "

`` + atr.getType().getTypeName());

`` }

}

class Test {

`` public Test( @Annotation Test test) {}

}

@Target ({ ElementType.TYPE_USE })

@Retention (RetentionPolicy.RUNTIME)

@interface Annotation {

}

Output:

sun.reflect.annotation.AnnotatedTypeFactory$AnnotatedTypeBaseImpl@12a3a380 Type = Test
