Hi all. I have a bunch of services, which implement a set of interfaces, and I
use a bunch of adapters to turn them into factories, making those services
protocol-independent.
The interface/adapter stuff works great and I'm able to expose those services
to several protocols, without changing a single line in them. However, some
of the protocols need some extra information to be passed, so I have to do
this:
factory = IFooFactory(myService)
factory.bar = "some value"
it works, but I'd rather use this:
factory = IFooFactory(myService, configurationObject)
which would take a second argument, an object implementing another interface
(e.g. IConfigurationDescriptor), containing all the necessary information for
that adapter. I don't want to put that information in the service, as it's
only useful to the protocol and would tie the service to a particular
protocol.
In order to implement this, registerAdapter would have to be able to take a
tuple of interfaces, like this:
components.registerAdapter(
AdaptToFactory,
(IFooService, IConfigurationDescriptor),
IFooFactory)
would that feature make sense? If so, I'll file an issue right now :-)
Cheers.
