Interface Reference<T>

All Superinterfaces:

org.comroid.api.SelfDeclared<Reference<T>>, org.comroid.api.Specifiable<Reference<T>>, java.util.function.Supplier<T>

All Known Subinterfaces:

Processor<T>, Reference.Settable<T>

All Known Implementing Classes:

FutureReference, OutdateableReference, OutdateableReference.SettableOfSupplier, Span

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 Reference<T>
