You can affect your provision logic based on bindings, sure.
public class SomeOtherModule {
@Override protected void configure() {
bind(ThingThatDependsOnAppProperties.class)
.toProvider(new Provider<ThingThatDependsOnAppProperties>() {
@Inject AppProperties appProperties;
@Override public ThingThatDependsOnAppProperties get() {
if (appProperties.isSomethingDefined()) {
return ...;
} else {
return ..;
}
}});
}
}
You can do the same with a provider method.
But this comes with the caveat that conditional bindings do make for tougher
debugging, and certainly less insightful static analysis.
