| @ParentProperty Annotation |
| |
| <p> |
| The {@link oaj.annotation.ParentProperty @ParentProperty} annotation is used to |
| identify a setter as a method for adding a parent reference to a child object. |
| </p> |
| <p> |
| A commonly-used case is when you're parsing beans and a child bean has a reference to a parent bean. |
| </p> |
| <p class='bpcode w800'> |
| <jk>public class</jk> AddressBook { |
| <jk>public</jk> List<Person> <jf>people</jf>; |
| } |
| |
| <jk>public class</jk> Person { |
| |
| <ja>@ParentProperty</ja> |
| <jk>public</jk> AddressBook <jf>addressBook</jf>; <jc>// A reference to the containing address book.</jc> |
| |
| <jk>public</jk> String <jf>name</jf>; |
| |
| <jk>public char</jk> <jf>sex</jf>; |
| } |
| </p> |
| <p> |
| Parsers will automatically set this field for you in the child beans. |
| </p> |
