Interface ConstructorResolver

All Known Implementing Classes:

ReflectiveConstructorResolver

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 ConstructorResolver

A constructor resolver attempts to locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.

The ConstructorExecutor will be cached, but if it becomes stale the resolvers will be called again.
