Hi,
I am in trouble to figure out how I can force the factories of iPojo
to
create an instance of a component.
In my case, I have a "manager" class that have an optional @Requires
on an
Array of plugins.
My problem is that if nobody use my "manager", no instance of this
manager
is created.
And in my case, it's the fact nobody use it because it's a "manager".
I found a simple workaround. When my manager implements also the Felix
Command interface, then the instance is created.
Could you help me to figure out what can be done to "force" the
instantiation without the workaround.
You can just set immediate="true" in your component type declaration:
@Component(immediate="true")
this will creates a POJO object as soon as your instance is valid (as
you have an optional service requirement, it will be immediately).
(components that do not provide any service are immediate by default)
I also tried with arch to dig into that problem and try to get a
list of
pending instantiations.
But I fail to find this. Don't you thing that this kind of feature
could be
helpful?
Your iPOJO instance should be listed with arch -instances. However
arch -instance your_instance_name says :
- I'm valid
- I have no created any POJO object
