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 ArgumentBinder<T,S>

An interface capable of binding the value of an Argument from a source


The selection of an ArgumentBinder is done by the ArgumentBinderRegistry. Selection could be based on type, annotation or other factors such as the request media type

Unlike TypeConverter instances binders can potentially handle complex objects and typically work on conjunction with a ConvertibleValues instance

An ArgumentBinder can either be registered as a bean or by META-INF/services. In the case of the latter it will be globally available at all times, whilst the former is only present when a io.micronaut.context.BeanContext is initialized
