[iPOJO] using External Handler
Hi,
In my previous post I mentioned an issue with my custom annotations.
Now I'm trying to write a iPOJO Handler to inject these dependencies.
I have created a class implementing PrimitiveHandler:
@Handler(name = "Channel", namespace = "com.ce.flowbeans.channels")
public class EventChannelHandler extends PrimitiveHandler {
I have implemented the required methods, but have only put some system.out for the moment.
I also have my annotation @Channel in the package "com.ce.flowbeans.channels".
When I startup the framework I see the handler:
>handlers
Handler org.apache.felix.ipojo:properties (VALID)
Handler org.apache.felix.ipojo:requires (VALID)
Handler org.apache.felix.ipojo:architecture (VALID)
Handler org.apache.felix.ipojo:callback (VALID)
Handler org.apache.felix.ipojo:controller (VALID)
Handler org.apache.felix.ipojo:provides (VALID)
Handler com.ce.flowbeans.channels:Channel (VALID) <==
But when a field in a component is annotated with the @Channel annotation, it gets not injected.
Neither do I see any call to the initializeComponentFactory(...) or configure(...) or start() methods of the handler.
Do I need to specifically attach the handler to the component instance in some way?
Thanks

Fw: [iPOJO] using External Handler
Posted by Michiel Vermandel <mv...@yahoo.com>.
Hi,
Yes everything is valid:
Handler com.ce.flowbeans.channels:Channel (VALID)
Factory com.ce.flowbeans.io.DeviceService (VALID)
Instance com.ce.flowbeans.io.DeviceService-0 -> valid
The issue is, I think, that the Handler is simply never called.
I have put some System.out in the constructor and the start method, but I do not see these comments in the console...
Any ideas?
Thnaks

If you take a look at the details of the instance (ipojo:instance <name>), what do you see ?
Is the factory of your component valid ?

Hi,
I have no clue why but today my custom handler is working with iPOJO 1.8.6.
I even removed the custom annotation on class level.
I must have gotten something wrong or out of sync the other day.
Thanks for the tips and the support.
I'm on my way again :-)
Regards,
Michiel

Hi,
I'll try, but it will probably be after the weekend.
Thanks already for the assistance!

Re: [iPOJO] using External Handler
Posted by Michiel Vermandel <mv...@yahoo.com>.
I changed my Handler to this:
@Handler(name = "ScanCustom", namespace = "com.ce.flowbeans.channels")
public class EventChannelHandler extends PrimitiveHandler {
Created the new Annotation:
package com.ce.flowbeans.channels;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.SOURCE)
public @interface ScanCustom {}
And changed my DeviceService class:
@Component
@Provides
@ScanCustom
public class DeviceService{
public static final String VOLUME_STATE_CHANGED="com/ce/flowbeans/io/VOLUME_STATE_CHANGED";
private DeviceWatcher deviceWatcher = null;
@Requires
EventService flowService;
@Channel(payload = DeviceBean.class, topic = VOLUME_STATE_CHANGED)
EventSender volumeStateChanged;
...
}
No change however...

Looking at your factory description, you can see that your handler is not
in the required handler's list.
Hmm I think I got it.
This is probably because of FELIX-3889
Runtime visible annotations cannot be iPOJO handler's markers.
Maybe you can simply have a class level marker annotation (not runtime
visible, probably no attributes, depending on what you need to read in your
handler). this annotation will enable your own handler.
And this handler will be able to read your own @Channel annotation

[iPOJO] using External Handler
Posted by Michiel Vermandel <mv...@yahoo.com>.
Hi,
I did not do that yet.
I just wanted to see the Handler getting invoked.
I have added a System.out in the constructor of the handler and in the start method but I do not see any of these comments in the console.
When exactly is/should the Handler be instantiated?
Thanks

Hi,
Did you implement the configure method and parsed the given metadata ? You must register a field interceptor for each field you need to inject.
