AW: Vectors

[Carsten Ziegeler <cz...@sundn.de>]

Hi,

in order to write a VectorDeserializer, I searched for a
definition of the Vector encoding - without success.
>From a wsdl demo, I find out that the soap vector is
encoded like the following:
<return xmlns:ns2="http://xml.apache.org/xml-soap" xsi:type="ns2:Vector">
   <item xmlns:ns3="item-namespace" xsi:type="item-type">
   </item>
   ...
   <item xmlns:ns3="item-namespace" xsi:type="item-type">
   </item>
</return>

So the only attribute available is the item-type attribute of the
item child-element.
So I have two questions:
- Is this the only information or must the Deserializer check for more?
- Is it allowed, that items may have different types?

Thanks,
Carsten

[Patch]: Deserializer for SOAP Vector

[Carsten Ziegeler <cz...@sundn.de>]

Hi,

attached is a patch for a Deserializer for the SOAPVector. 
It consists of the Deserializer itself, a diff for 
the registry (which adds the Deserializer) and a diff
for the Emitter to generate correct java code.

Thanks,

Carsten
