Niclas Hedhman commented on QI-364:
-----------------------------------
Would it really be better to have 2 interfaces and 2xN methods, instead of 1xN
method, 1 interface and 1 adapter??
With Paul's proposal, Activator and Passivator seems like reasonable names, but
if it is only 1 interface, the name is not totally correct. Something like
LifecycleControl. Perhaps that naming issue by itself is good enough reason to
have 2xN methods.

> Key: QI-364
> URL: http://team.ops4j.org/browse/QI-364
> Project: Qi4j
> Issue Type: New Feature
> Reporter: Niclas Hedhman
> Priority: Blocker
> Fix For: 2.0 - Reductionism
>
>
> In 1.x, Activatable was used to get Services up and running. However, I feel
> that the concepts are mixed up in a bad way, since Activatable initially
> relied on that the Activatable method was exposed like any other method, and
> that there could only be one. Later, we added that any Mixin that got
> instantiated, would have its Activatable methods called. But, a pure Mixin
> for only the purpose of starting up the service couldn't really be supported.
> Further, internally in Qi4j Runtime, there is an Activation mechanism in
> place;
> * User "activate" the application.
> * The Application activates the Layers.
> * Each Layer activates the Modules.
> * Each Module activates the Services (if instantiateOnStartup).
> The current system is fragile (if a Mixin with the start-up code has its
> method(s) overridden it will not be instantiated), and we need to find a new
> solution. This will break compatibility, so it is imperative that this is
> solved prior to 2.0 release.
> Action item 1; *Remove Activatable interface*
> There are possibly a few ways to provide this functionality, listed in
> individual comments below.
