We can provide a default implementation in IDetachable. This will make
IReadableModel a FunctionalInterface:
public interface IJava8Detachable extends Serializable {
default public void detach() {
}
}
@FunctionalInterface
public interface IJava8ReadableModel<T> extends IJava8Detachable {
public T getObject();
}
@FunctionalInterface
public interface IJava8WriteableModel<T> extends IJava8Detachable {
public void setObject(T object);
}
A method defining the readable model as a parameter:
public <T> void setSomeReadableModel(IJava8ReadableModel<T> m) {
...
}
Usage scenario:
setSomeReadableModel(() -> "Foo " + System.currentTimeMillis());
