An alternative approach is Fortress as a container. In this context
we would be looking at Fortress implementing the Merlin Block
interfaces. This is similar to the above (because Block is an
Appliance). The difference between Block and Appliance is that a
Block manages a set of contained appliances.
Is the containment hierarchy container -> block -> appliance? Where an
appliance can be a block and thus it becomes recursive?
-pete
ApplianceContext <--- all of the deployment info (config, custom
context entries, meta, lifestyle policy, lifecycle strategy, etc.)
Appliance <-- handles deployment and decommisssioning of components
based on the supplied context in response to access and release
requests (e.g. Object = appliance.access( this ) returns fully
established component).
Block <-- extends Appliance by (a) doing additional management of
its implememntation (where block implementation referes to the
components heirachy it is managing), and (b) publishes services
established via the implementation as dynamic meta info - i.e.
a block transforms itself into a normal component in that it
exposed depedencies and services and can be applied as a
solution when building other components. Implemntation of (b)
is currently in-progress.
Thus, yes, it is recusive.
Cheers, Steve.
