RE: Implementation Pluggability

The link below only talks about intercepting 'set' calls using prePostSet construct.

Is there a similar mechanism for intercepting 'get'  calls as well ?

I found this page : http://dev2dev.bea.com/technologies/xmlbeans/articles/Configuring_XMLBeans.jsp

It pretty much explains everything.

Thanks for the prompt reply.

Can I do the same thing for get calls as well ?

Is there something like a preGet and a postGet as well ?

You can use a schema configuration file (.xsdconfig) to specify an extension class to be called when set get calls occur :

 

1) Put such a directive for the compiler to generate the callbacks in your schema generated classes :

 

<xb:config xmlns:xb="http://xml.apache.org/xmlbeans/2004/02/xbean/config"

               xmlns:dto="http://www.cgi.com/awfm/dto">

                            

   <xb:extension for="">

            <xb:prePostSet>

                        <xb:staticHandler>fully qualified name of the class the implements the callback static  functions</xb:staticHandler>

            </xb:prePostSet>        

   </xb:extension>

  

</xb:config>

 

2) implement a class for the call backs…

 

  public static void postSet(int opType, XmlObject xo, QName propertyName, boolean isAttr, int index)

  public static boolean preSet(int opType, XmlObject xo, QName prop, boolean isAttr, int index)   

 

3) Check xmlbeans for actual and recent info, but this works for 1.0.3…

 

Good luck…

Hi,

I am investigating the use of XML Beans on a project and I had the following question - I have the requirement to be able to intercept the getX and getY calls and add custom logic. Is there anyway in which this can be accomplished - like generating a custom sub class ( my sub class) of org.apache.xmlbeans.impl.values.XmlObjectBase ?

 

Thanks
