Well, I made it to the FAQ on the wiki and there is the answer, top of the
FAQ. *idiot*
I am now trying to implement my slightly complicated problem. Instead o
strings, I want the annotation to be to a class. So I have:
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD, ElementType.PARAMETER})
@BindingAnnotation
public @interface WhisperId {
}
public class MurmurModule extends AbstractModule {
private final WhisperIdentity serverId;
public MurmurModule(WhisperIdentity serverId) {
this.serverId = serverId;
}
@Override
protected void configure() {
bindConstant().annotatedWith(WhisperId.class).to(serverId);
}
}
The call to to(...) is blowing up. It says:
Bound mismatch: The generic method to(E) of type ConstantBindingBuilder is
not applicable for the arguments (WhisperIdentity). The inferred type
WhisperIdentity is not a valid substitute for the bounded parameter <E
extends Enum<E>>
and WhisperIdentity is not an Enum.
Ok, thinking about it a bit, I need to pass in the primitive types to the
Module, build my WhisperIdentity in there and then inject that puppy. Does
that sound about right?
Thanks,
Rob
