Setting and getting properties in iPojo
Hello,
I'd like to know if there is an easy way to set and get properties of a component by another one (in a different bundle, assuming this is iPojo that validate/invalidate each component). In a short way, I'd like to have a component that is able to introspect another component as soon as its instance is created (but before the validation) and set some properties and get those properties (assuming they changed) after the invalidation (and before any destruction on the instance).
Thanks
Regards,

Hi,
This seems to be the feature I was looking for. I will try to learn more about it and try it to see if it fits :-)
Thanks,
Regards.

Yes, there is a system property (org.apache.felix.ipojo.handler.auto.primitive) letting you attaching handlers to all (primitive) instances. The value is a comma separated list. Each element is the fully qualified name of the handler (namespace:name).

Hi,
You can do what you want with:
* the Architecture service (exposed by all instances by default) for the introspection
* the iPOJO API for the property manipulation (http://felix.apache.org/site/apache-felix-ipojo-api.html)
Regards,
Clement

I'd not like to use a handler because a developper would need to declare it in each components (and this is a handler that will be declared in each components). That seems very intrusive for me. Instead, I'd like a component that is able to introspect, through Ipojo, the properties of another component and set some properties if needed. That seems less intrusive for me because the developper doesn't need to care about this aspect. But the Ipojo API doesn't seems to let me do that easily :-/

Not sure, but it sounds like more of a job for a custom handler than a
component.
Maybe Clement has better advice...
