I've seen this snippet:
@Component(modules = {TestActivityModule.class})
public interface TestActivityComponent {
void inject(TestActivity activity);
}
But the inject
method is not implemented in user code (but auto-generated in Dagger-2
code).
So is the inject
a reserved name? how Dagger-2
knows to implement this method?
Ok, I got it: the name doesn't matter, it can be e.g. squeeze
, as long as the provided type contains @Inject
fields(s)/methods(s)/constructor(s), Dagger-2
will generate the method's body:
@Component(modules = {TypoModule.class})
public interface TypoComponent {
void squeeze(Thingie t);
}
...and as long as there's a @Provides
that returns the @Inject
ed type:
@Module class TypoModule {
@Provides InjectedType whateverNameYouDecide() {
return new InjectedSubType();
// InjectedSubType extends InjectedType, obviously...
}
}
Of course, Thingie
should have @Inject
ed member or nothing will happen:
class Thingie {
@Inject InjectedType thingieID;
}
That's the whole story...
