Interface Injector

@Deprecated(forRemoval=true, since="4.0.8") public interface Injector
Deprecated, for removal: This API element is subject to removal in a future version.
Helidon inject is deprecated and will be replaced in a future version
Used to perform programmatic activation and injection.

Note that the reference implementation of Injection only performs non-reflective, compile-time generation of service activators for services that it manages. This Injector contract is mainly provided in order to allow other library extension implementations to extend the model to perform other types of injection point resolution.
