I'm looking for any recommendations as to the best pattern to
accomplish a sort of meta-data-driven resolution of service 'groups'
using WinsorContainer.
Let's say I have multiple instances of each implementation registered
with the container, each one given a service id that in some way
associates it with the 'group'. For instance, imagine the following:
type: IServiceInterface1
service: TheTopService
id: "customer1.service1"
type: IServiceInterface2
service: TheDependentService
id: "customer1.service2"
type IServiceInterface1
service: AnotherService
id: "customer2.service1"
In some cases, I need the hierarchy of objects resolved from the
container with keys prefixed with "customer1" and in other cases I
need the hierarchy of objects resolved from the container with key
prefixed with "customer2".
Obviously I can always ask the container for the service by its
explicit id as in...
IServiceInterface1 theService =
container.Resolve<IServiceInternface1>("customer1.service1");
...and...
IServiceInterface1 theService =
container.Resolve<IServiceInternface1>("customer2.service1");
...but at run-time, I'd rather the code asking the container to
perform the resolution NOT have any awareness of having to ask things
by service id. This gets exponentially more complex because even were
I willing to accept the use of the id value at the initial call to
Resolve<T>, I would still need to start registering specific service
overrides for all of the dependencies that the parent objects in turn
have for themselves.
Basically, in a nutshell I have the need to register mutiple parallel
hierarchies of objects with the container and then (in the simplest
manner possible) have the container return either one entire object
hierarchy or another based on some discriminator strategy.
I'm curious whether anyone has any experience with this kind of an
approach...would I be better off simply using a completely separate
WindsorContainer instance for each of the separate discriminators I
expect (e.g., one container for objects for 'client1', another for
objects for 'client2', etc. in my above example)?
Recommendations as to the cleanest way to attack this would be
welcome.
Thanks in advance,
-Steve B.
