Subject [jira] Commented: (AXISCPP-573) problem in setURI() API in IAttribute class
Date Tue, 07 Jun 2005 07:09:44 GMT
    [ http://issues.apache.org/jira/browse/AXISCPP-573?page=comments#action_12312843 ] 

Dushshantha Chandradasa commented on AXISCPP-573:
-------------------------------------------------

Here the problem is that the method setURI (const AxisChar* uri) just set a string variable.
The engine uses the prifix which is also a string variable in the Attribute object to get
the namespace declaration. If we call the setURI(const AxisChar* uri) method while there is
a prevously set  prefix, it only changes m_uri string variable in the Attribute object which
is the return value of getURI() method. Engine still uses the namespace prefix to get the
namespace declaration. 

I think , removing the setURI() from the API list is not a good idea as one need to set the
URI when the prifix is empty. 

Among the other two options, the best one is option 1. Here if there is a previously set prefix,
setURI() shoul dautomatically set the prefix accordingly. And there is no predefined namespace
with that URI, the prefix should be set to empty.

Any thoughts on this???

> If the prefix of the attribute is empty and if I use setURI() then the Attribute class
correctly serialize by adding the correct prefix and if necessary will even add the namespace
declaration to the serialized output.
> IAttribute *attr1=phb->createAttribute("Name","","axis");
> attr1->setURI("http://axis.apache.com");
> will create the following soap message
> <ns:TestHeader xmlns:ns="http://ws.apache.org/" xmlns:ns2="http://axis.apache.com"
ns2:Name="axis">
> Here setURI() results in generating a namespace declaration for the uri "http://axis.apache.com"
and used the generated prefix 'ns2' as the prefix for 'Name' attribute.
>  But if the attribute prefix is not empty, then this setURI() does not change its prefix.
> INamespace *nsp=phb->createNamespaceDecl ("nsp","http://apache.com");
> IAttribute *attr1=phb->createAttribute("Name","nsp","axis");
> attr1->setURI("http://axis.apache.com");
> results in 
> <ns:TestHeader xmlns:ns="http://ws.apache.org/" nsp:Name="axis" xmlns:nsp="http://apache.com">
> attr1->getPrefix() will return 'nsp'
> attr1->getURI() will return 'http://axis.apache.com'
> but there is no namespace declaration for this combination.
> So either
>  1.setURI() should also change the prefix value accordingly.
>  2.setURI() should not change the URI if prefix is already set.
>  3.setURI() should be removed from the API list.
