Interface TargetContextResolver<T extends Message>

Type Parameters:
T - the type of Message to resolve the context for
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 TargetContextResolver<T extends Message>
