Hi,
I would like to create a mapping for the following domain object.
class Person {
private Person employer;
private Set<Person> employees;
public void addEmployee(Person employee) {
employee.setEmployer(this);
this.employees.add(employee);
}
public void setEmployer(Person employer) {
this.employer = employer;
}
}
Each person has one employer and many employees. The relationship is
bi-directional as you can see from the code above. The bi-directional
relationship is managed by method Person#addEmployee. You can see that
when add an employee to a person will in turns set the employee's
employer automatically.
The problem here is that, when using JiBX library to construct objects
from XML file, the standard mapping approach does not use
Person#addEmployee method, but it map class members directly. The XML
file using is look like this:
<person>
<name>James Clark</name>
<employees>
<person>
<name>James Iha</name>
</person>
<person>
<name>James Brown</name>
</person>
</employees>
</person>
From the XML file, there is no element to be mapped to Person#employer
field. Therefore, when construct objects from XML file, all employer
reference in each Person object are gone.
So here is the question, how can I maintain the reference in
Person#employer field when unmarshalling from XML?
Regards,
