Re: multi references

[Manish Balsara <ma...@aumsoft.com>]

Let me try giving an example of arrays to indicate multi-references,

public class Animal
{
	public KeyValue(String type)
	{
		// code deleted for brevity
	}
}

Animal a1 = new Animal("dog");
Animal a2 = new Animal("cat");

Animal animalArray[] = new Animal[3];
animalArray[0] = a1;
animalArray[1] = a2;
animalArray[2] = a1;

when the array is marshalled, you could represent it as distinct elements,
(without multiple references). When the array gets unmarshalled it would
have 3 distinct objects and there would be no way to know that the
first and third elements pointed to the same object:
<SOAP-ENC:Body>   
...
<animalArray SOAP-ENC:arrayType="Animal[3]">
  <animal><type>dog</type></animal>
  <animal><type>cat</type></animal>
  <animal><type>dog</type></animal>
</animalArray>
...
</SOAP-ENC:Body>

OR

you can represent the data with multi-reference accessors, so that when
the array is unmarshalled, the first and third elements are the same
objects at the receiver, as they were on the sender's.
<SOAP-ENC:Body>
...
<animalArray SOAP-ENC:arrayType="Animal[3]">
  <animal href="#1"/>
  <animal><type>cat</type></animal>
  <animal href="#1"/>
</animalArray>
<animal id="1"><type><dog></type></animal>
...
</SOAP-ENC:Body>
