Handler

public class DefaultInjectionProvider
extends StandardInjectionProvider

The injector's default instantiation provider. Extending StandardInjection, it roughly follows the documentation of Inject with additional restrictions:

• An exception is thrown if a class with an @Inject constructor also has fields with @Inject. In parent classes, @Inject fields are accepted.
• @Inject fields may not be static.
• This handler also checks that the class to instantiate is in the allowed root package.
