Hi all,
I want to have a DS Component Factories that will be able to create
different instances of my
component.
My component class implement the EventHandler interface, so it will
receive event notification by
Event Admin Service.
An example of one of my component factory is this one:
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="org.my.components.mycomponentFactory"
factory="my.mycomponent">
<implementation class="org.my.components.MyComponent"/>
<service>
<provide interface="org.osgi.service.cm.ManagedService"/>
<provide interface="org.osgi.service.event.EventHandler"/>
</service>
</scr:component>
As i've learn an Event Handler could specify a topic filter with the
property: "event.topics or EventConstants.EVENT TOPIC"
My problem is that i want my components will subscribe to different
topics according to a value that i set in the
properties when i'll call ComponentFactory.newInstance.
For example if in my properties there a topic id i want my component
generatye with the factory to subscribe to something like:
BASE_TOPIC/TOPI_ID
It's enough to create the property "event.topics or EventConstants.EVENT
TOPIC" with the right value before calling the newInstance method
or i need additional step??.
Thanks
Andrea Zoppello
