service+configuration - how?
Hi!
I currently use hivemind to retreive instances of interface-implementations.
(instanciation of a class for the service-interface).
I'd like to combine this with some specific properties for configuring
the implementation.
I find the examples on configuration-points and contributions somewhat
hard to understand. (It seems that I have to create a separate class for
the config - and call this from the implementation - instead of
declaring it all in the Hivemind config-file).
What I would like is some private static variables in the
implementation-class to be set when instanciated.
Lets's say this is the iface:
interface IMyService {
public void methodA();
}
and the implementation:
public class MyService implements IMyService{
final static private String aStringProp;
final static private Integer anIntegerProp;
public void methodA(){
//do something
}
}
how could I do this the easiest way through the use of HiveMind, such
that when I retrieve the service through the registry, the constructed
object would automatically have it's properties set?
I'd rather avoid having a separate class for configuration as I find
this too fine-grained.
Thanks in advance - and thanks for a great API!
Kind regards,
David Karlsen

The hivemind.BuilderFactory exists to configure your service
implementation using dependency injection.
