abstract class Injector extends AnyRef
An injector used within Finatra.
This is abstract class to allow for two implementations:
- production injector, created via Injector.apply and
- test injector, created via TestInjector.apply
DO NOT EXTEND this class on your own.

Abstract Value Members
- abstract def instance[T](key: Key[T]): T
Returns the appropriate instance for the given injection key.
Returns the appropriate instance for the given injection key.
When feasible, avoid using this method in favor of having the Injector inject your dependencies ahead of time via annotating your constructor with
@Inject.- T
type of the bound instance to return from the object graph.
- key
com.google.inject.Key binding key of the bound instance to return from the object graph.
- returns
bound instance of type T represented by com.google.inject.Key key.
