Suppose that you have a TypeLiteral analogue in some other library, which
can be easily constructed from TypeLiteral via exporting TypeLiteral's
getType() to the analogue's TypeLiteral.of() counterpart (or custom
subclassing shenanigans). Examples of this may include
org.apache.commons.lang3.reflect.TypeLiteral (or the Typed interface...) or
com.fasterxml.jackson.databind.TypeReference (though ultimately the goal is
the non-generic JavaType...). The common thing is that these objects have
only one dependency, and that is on a TypeLiteral. The question is that,
given that the only dependency is TypeLiteral, is it possible to define a
"broadly-applicable" binding, or will I be forced to enumerate types? And
when I mean "broadly-applicable", it could be either an automatic injection
(similar to how TypeLiteral itself is injected) restricted to the types
known by the injector, or "any type" including those that the injector does
not (for example, via injector.getInstance(new TypeLiteral<Foobar>() {}),
where Foobar was not used in the construction of the injector).
Also related: suppose in an assisted injection context TypeLiteral is your
only unassisted dependency, like the following:
public interface TypedObjectFactory<T> {
public TypedObject<T> build(T object);
}
public class TypedObject<T> {
@Inject
public TypedObject(TypeLiteral<T> type, @Assisted T object) { ... }
}
Is it possible to have a "broadly-applicable" installation (in this case,
install FactoryModuleBuilder in broad terms like the above), or will I be
forced to enumerate types?
