Interface ArgumentTypeLookup<S extends CommandSource>

Type Parameters:
S - the source type
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 ArgumentTypeLookup<S extends CommandSource>
Functional interface for resolving nested/component types during argument type resolution.

This interface is passed to ArgumentTypeHandlers to allow them to recursively resolve ArgumentType instances for nested generic type parameters.
