[aspectwerkz-user] Getting attribute parameter in an advice

Hi,

 

I am trying to pass parameters to the aspects, however, I would like to get
finer granularity than the "param" support in aspects, i.e. I have multiple
advices declared in a single aspect, and I would like to get different
values of parameters for each invocation of advice.

 

Aspectwerkz2.dtd specifies an "attribute" attribute to the advice XML
element. I was trying to write a code to enable me to do this.

I am trying to use the AdviceDefinition object to retrieve the attribute
using the getAttribute(). So, the code snippet that I am trying to use is:

 

        SystemDefinition sd =

            SystemDefinitionContainer.getDefinitionFor

                (Thread.currentThread().getContextClassLoader(),
"systemname");

        Collection coll = sd.getAdviceDefinitions();

        Iterator itr = coll.iterator();

        while (itr.hasNext())

        {

            AdviceDefinition ad = (AdviceDefinition)itr.next();

            if ("advicename".equals(ad.getName()))

            {

                System.out.println("ad.getAttribute() = " +
ad.getAttribute());

                System.out.println("ad.getExpressionInfo().toString() = " +
ad.getExpressionInfo().toString());

            }

        }

 

I am getting the expression correctly, but the advice "attribute" as null.

 

The aop.xml looks something like this:

 

    <system id="systemname">

 

        <package name=".">

            <aspect class="BootstrapAspect" deployment-model="perJVM">

 

                <pointcut name="." expression="."/>

 

                <advice name="advicename" type="around"

                        bind-to="."

                        attribute="attribValue"/>

 

.

 

I cannot see the method setAttribute() being called from anywhere in the
aspectwerkz codebase.

Is this feature supported/working?

 

 

Thanks and regards,

Sameer
