jOOQ / jOOL

jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.

Support void/no-arg function wrapping in Unchecked? #317

Closed leaumar closed 7 years ago

leaumar commented 7 years ago

I seem to be missing a helper function in Unchecked that would allow me to wrap a method that neither takes arguments nor returns anything, just performs work and might throw an exception. I can find neither it nor a note explaining why it isn't there.

I mean something like this: image

Is there a reason why it doesn't exist, or could it be added in an update?

Is there a FunctionalInterface in the JVM with a void no-args method that throws an Exception to reuse? Runnable doesn't throw an exception, so it wouldn't fit the bill here.

org.jooq.lambda.fi.lang.CheckedRunnable seems to be the type you're looking for.

leaumar commented 7 years ago

Indeed, thanks! Overlooked it because I linked it with threading and those kind of Runnables...

lukaseder commented 7 years ago

Yeah, it's a historic type also in the JDK: java.lang.Runnable. There's no new Java 8 functional interface of that type, given that Runnable is already sufficient.
