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.
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 'goes stale' the resolvers will be called again.
