You mean, do something like this in the module class?
@Provides
public Settings getSettings(InjectionPoint ip) {
TypeLiteral<?> type = ip.getDeclaringType();
Namespace ns = findNamespace(type);
String namespaceName = ns == null ? Namespace.DEFAULT : ns.value();
return settingsForNamespace.get(namespaceName);
}
It sounds great - clean and elegant. Alas, it doesn't work :
"Could not find a suitable constructor in
com.google.inject.spi.InjectionPoint. Classes must have either one (and
only one) constructor annotated with @Inject or a zero-argument constructor
that is not private."
Maybe there is some other type that *could* be injected that would provide
a path to the InjectionPoint? InjectionPoint is definitely the thing I
need to get hold of...
Thanks!
