Re: How does using Interface for mapping object-to-xml works in Betwixt?

[robert burrell donkin]

hi

i've set up some tests using the source provided but i'm afraid to say 
that i don't seem to be able to reproduce your problem.

i suspect that your using some .betwixt files and maybe there's a 
problem somewhere there.

could you either post you .betwixt files or (even better) a unit test 
that i can run and demonstrates the problem.

I seems to have different result when i map an object-to-xml  using an 
object instance as compared to that of an interface.

The scenario is as such:
I have a Person class which implements an interface PersonIntf and 
when this object is mapped into xml using the Person instance, i have 
the following result
  <person age="21" name="John Smith">
      <address street1="Street1" postalcode="12345"/>
  </person>

but when i used the same Person object instance but now using the 
PersonIntf via the XMLInspector.setClassNormalizer() i have the 
following result - the <address> element info are all missing
  <person age="21" name="John Smith">
      <address street1="" postalcode=""/>  <!-- street1 & postalcode 
not being mapped -->
  </person>

Did i missed something here? I suspect that the XMLIntrospector did 
not include the super interface of PersonIntf => AddressIntf, am i 
right?

I have all my classes listed below, i am using the nightly build 
downloaded last night.

Any help will be greatly appreciated. Thanks in advance

===Address Interface Class ===
public interface AddressIntf {
    public String getStreet1();
    public int getPostalcode();
    public void setStreet1(String st);
    public void setPostalcode(int pc);
    //convenience method
    public void setAddress(String st, int pc);
}

===Person Interface Class===
public interface PersonIntf extends AddressIntf{
    public String getName();
    public int getAge();
    public void setName(String name);
    public void setAge(int age);
    //derive attr
    public AddressIntf getAddress();
}
===Person Class===
public class Person implements PersonIntf {
    private String name;
    private int age;
    private Address address;
    public Person() {address = new Address();}

    public Person(String name, int age) {
       this(name, age, null, 0);
    }
    public Person(String name, int age, String street1, int 
postalcode){
        this.name = name;
        this.age = age;
        this.address = new Address(street1, postalcode);
    }

    public String getName() { return name;}
    public void setName(String name) {this.name = name;}
    public int getAge() {return age;}
    public void setAge(int age) {this.age = age;}
    public AddressIntf getAddress() {return address;}
    public void setAddress(Address address) {this.address=address;}
    public void setAddress(String st, int pc) {address.setAddress(st, 
pc);}

    public String getStreet1(){ return address.getStreet1();}
    public void setStreet1(String st){ address.setStreet1(st);}
    public int getPostalcode(){ return address.getPostalcode();}
    public void setPostalcode(int pc){address.setPostalcode(pc);}
    public String toString() {return "PersonBean[name='" + name + 
"',age='" + age + ", address[" + address +"']";}

    private class Address implements AddressIntf {
        private String street1;
        private int postalcode;
        /** Creates a new instance of Name */
        public Address() {}
        public Address(String street1, int postalcode){
            this.street1=street1;
            this.postalcode=postalcode;
        }
        public String getStreet1() {return street1;}
        public void setStreet1(String street1) {this.street1 = 
street1;}

        public int getPostalcode() {return postalcode;}

        public void setPostalcode(int postalcode) {this.postalcode = 
postalcode;}

        public void setAddress(String street1, int postalcode){
            this.street1=street1;
            this.postalcode=postalcode;
        }
        public String toString(){return "street1="+street1+", 
postalcode="+postalcode;}

    }
}
