JBossAOP Metadata Question

[sushmam]

Hi,

I'm able to obtain the metadata (defined in jboss-aop.xml) only in case of MethodInvocation.

For ConstructorCalledByConstructorInvocation, ConstructorCalledByMethodInvocation, MethodCalledByMethodInvocation, I'm not able to get the metadata.

Why isn't the metadata getting picked up for the above mentioned invocations?

I looked into the jboss-aop sources, and found that in MethodInvocation.java, getMetadata method, if the threadlocal variable returns a null value for the metadata, we try and get the metadata from the ClassAdvisor.

In case of ConstructorCalledByConstructorInvocation, no such attempt is made. If the threadlocal variable returns a null value for the metadata, the same is returned from the getMetadata method. Is there a specific reason for doing so?

Can anyone throw some light on this please?
(I'm using JBossAOP 1.0 Final)

========================================
Here is how i'm defining the metadata in jboss-aop.xml

<metadata tag="mname" class="xyz">
<method expr="void send(boolean)">
 <method_name>MetaOne</method_name>
</method>
</metadata>

<metadata tag="mname" class="abc">
 <constructor expr="abc(byte\[\], boolean)">
 <method_name>MetaTwo</method_name>
</constructor>
</metadata>

<!-- MethodCalledByMethodInvocation -->
<bind pointcut="withincode(public void xyz->send()) AND call(* xyz->send(boolean))">
<interceptor class="TestMetricsInterceptor"/>
</bind>

<!-- ConstructorCalledByMethodInvocation -->
<bind pointcut="call(public abc->new(..))">
<interceptor class="TestMetricsInterceptor"/>
</bind>

The invoke() of interceptor where I'm trying to get the meta-data is:

public Object invoke(Invocation invocation) throws Throwable {
 InvocationBase invocationBase = (InvocationBase) invocation;
 System.out.println("Metadata ******** " + invocation.getMetaData("mname", "method_name"));
}

Only if the invocation is of type MethodInvocation, I'm able to get a valid metadata. For the other invocations, I get metadata as null.

========================================

Thanks,
Sushma.
