[wsf-c-dev] [C++] How should this be implimented in C++?

[Dimuthu Gamage]

Hi Senaka,

Here  you can follow the approach in the Java API,

There class hierarchy is

interface org.apache.axiom.om.OMNode

    * interface org.apache.axiom.om.OMComment
    * interface org.apache.axiom.om.OMDocType
    * interface org.apache.axiom.om.OMElement (also extends 
org.apache.axiom.om.OMContainer)
    * interface org.apache.axiom.om.OMProcessingInstruction
    * interface org.apache.axiom.om.OMText

So the C++ users never need to really deal with OMNode directly like it 
happened to axis2/c users(to traverse node), rather they will work 
directly with the subclasses since they have all the node functions as 
well (From inheritance). Then there won't be any requirement to return 
the data element, so the  function you mentioned is not required for C++.

Thanks
Dimuthu
