Re: [aspectj-dev] Clarification of concrete aspect implementation whethe

[sridhar thiyagarajan <sridharthiyagarajan@xxxxxxxxx>]

Many thanks for the response .. Andy. Could you please help me about the attribute to be added in the below concrete aspect definition that controls the object creation and the possible values for it.

  <concrete-aspect name="main.java.aop.field.MyFieldAspect">
    <around pointcut="get(@main.java.aop.field.Field * *)" invokeClass="main.java.aop.field.FieldAspect" invokeMethod="getField()"/>
  </concrete-aspect>

Thanks.

Yep, if you don’t specify then it is singleton.

Hello,

I am using concrete aspects in my project. Could anyone please help me to understand whether the implementation objects of concrete aspects defined in the below aop.xml are singleton.

Please confirm my understanding that there will be only one instance of concrete-aspect implementation created for each concrete aspect definition in the aop.xml generated by the aspectJ. JFYI that load time weaving is employed in my project.


<?xml version="1.0" encoding="UTF-8"?>
<aspectj>
<aspects>

  <concrete-aspect name="main.java.aop.field.MyFieldAspect">
    <around pointcut="get(@main.java.aop.field.Field * *)" invokeClass="main.java.aop.field.FieldAspect" invokeMethod="getField()"/>
  </concrete-aspect>

  <concrete-aspect name="main.java.aop.extend.ConcreteTracingImpl">
    <around pointcut="execution(@main.java.aop.method.Method * *(..))" invokeClass="main.java.aop.extend.AbstractTracing" invokeMethod="traceMethod()"/>
  </concrete-aspect>

</aspects>
<weaver options="-verbose -showWeaveInfo" />
</aspectj>

Thanks.
