FactoryFor ( iface )

Config key for an IComponentFactory that returns iface objects

Usage:

        key = config.FactoryFor(ISomething)

The example is equivalent to:

        key = config.MultiKey(binding.IComponentFactory, ISomething)

ProviderOf ( iface,  *classes )

Configuration key based on interface+class(es)

Usage:

        key = config.ProviderOf(ISomething, Class1, Class2, ...)

The example is equivalent to:

        key = config.MultiKey(ISomething, config.UnionOf(Class1, Class2, ...))

In other words, the returned key is a two-element configuration key that matches the combination of the given interface and any of the given classes.
