I have several classes implementing interface Provider<Communication> and
I'm using Guice with a @Named annotation to bind them as required, e.g.:
@Singletonpublic class Verizon implements Provider<Call> {
...}
@Singletonpublic class TMobile implements Provider<Call> {
...}
bind (new TypeLiteral<Provider<Call>>() {}).annotatedWith(
Names.named("Verizon")).to(Verizon.class);
bind (new TypeLiteral<Provider<Call>>() {}).annotatedWith(
Names.named("TMobile")).to(TMobile.class);
Is there a clean way to implement a factory that takes the name as a
parameter, e.g.:
public static <C extends Communication> Provider<C> getCallProvider(C
communication) {
String providerName = communication.getProviderName();
return [Guice's matching object for type Provider<?> and @Named =
providerName];}
