Interface BeanDefinitionInjectionPointResolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface BeanDefinitionInjectionPointResolver

Resolves injection point shapes which are not part of the core Java type model.

Language integrations can use this extension point to map collection-like, optional, or other language-specific types to one of the standard BeanDefinitionInjectionPoint implementations. Returning an empty optional lets the core processor treat the requested type as a single bean.

Since:

5.2.0
