Hi,
I'm just looking at lambdaifying a private branch of the library
Functional Java for fun, and have downloaded today's Lambda edition of
Java 8.
FJ's 'function' class, F, is unfortunately a class not an interface,
with a lot of final instance methods, and the lambda conversion only
targets interface types, not class types, so that needs converting to
an interface. I'm hoping to do that using extension methods so that
callers don't need changing, but I can't seem to make extension
methods work or even be recognised by the compiler. As far as I can
gather, they should look like this:
void foo() default {
System.out.println("Subtype was too lazy to define foo(), so we're
using this default.");
}
The compiler just reports that it expects a ; where I have 'default',
which is what I'd expect on Java 7 or earlier.
Is there somewhere I can look to see the status of that integration,
or if my syntax is wrong here where can I see the correct syntax?
Also, is 'final' ok there instead of 'default'?
Cheers,
Ricky.
