@ParentProperty Annotation

The @ParentProperty annotation is used to identify a setter as a method for adding a parent reference to a child object.

A commonly-used case is when you're parsing beans and a child bean has a reference to a parent bean.

public class AddressBook {
    public List people;
}

public class Person {

    @ParentProperty
    public AddressBook addressBook;  // A reference to the containing address book.

    public String name;

    public char sex;
}

Parsers will automatically set this field for you in the child beans.
