Description

I have a POJO class using method chaining such as :

public static class CustomChainingPojoType {
private String myField1;
private int myField2;

public CustomChainingPojoType() {
}

public CustomChainingPojoType setMyField1(String myField1) {
this.myField1 = myField1;
return this;
}

public CustomChainingPojoType setMyField2(int myField2) {
this.myField2 = myField2;
return this;
}

public String getMyField1() {
return myField1;
}

public int getMyField2() {
return myField2;
}
}

 

It can not be analyze as POJO in TypeExtractor because the set method return type is not Void, How about add a condition that return type can be class self.
