public class AdapterInjector extends java.lang.Object implements MembersInjector<IAdaptable>
MembersInjector
that supports injection of adapters into
an IAdaptable
implementation class'
IAdaptable.setAdapter(TypeToken, Object, String)
method, that is
marked as being eligible for adapter injection (see InjectAdapters
).
Being registered for a specific IAdaptable
an AdapterInjector
will inject all instances of that type or any sub-type, evaluating all
AdapterMap
bindings that can be obtained from the Injector
,
which was forwarded to it via setInjector(Injector)
. It will inject
all adapters, for which adapter (map) bindings with a matching
AdapterMap
annotation exist. Here, matching means, that the type
provided in the AdapterMap
annotation of the IAdaptable
#s
method ( AdapterMap.adaptableType()
) is either the same or a sub-type
of the type used with the AdapterMap
annotation of the related
binding.
The AdapterInjector
supports that type information about the actual
adapter type may be omitted from the adapter map binding (i.e. the used
AdapterKey
only provides a role but no type key). It will try to
infer the actual adapter type from respective bindings, or fall back to the
type inferred from the adapter instance (which will not be adequate for
generic types because of type erasure) in such a case.
