Kamil commented on WICKET-6396:
-------------------------------
[~mgrigorov] me too :) But I understand that because of lack of Inheritance
they fit just for specific needs, hence shouldn't be wicket-wide (that is why I
have them tailored to me in my project).
Funny thing is Java9 will introduce List.of, Set.of etc, so maybe there is a
reasoning behind it...
[~svenmeier] So we all agree that
{code}
IModel<Boolean> isPresent()
{code}
and
{code}
IModel.toOptional()
{code}
are necessary but you don't like:
{code}
public <X extends Throwable> T orElseThrow(Supplier<? extends X>
exceptionSupplier) throws X;
{code}
and
{code}
public void ifPresent(Consumer<? super T> consumer);
{code}
because they don't return Model nor boolean?
> Model should provide other Optional's methods
