Annotation Interface Parallel

@Incubating
@Documented
@Retention(SOURCE)
public @interface Parallel

Runs each iteration of an annotated for loop in parallel using the current pool or default executor, with structured completion.

Uses Pool.current() if inside a ParallelScope.withPool(int, java.util.function.Function<groovy.concurrent.AsyncScope, T>) block, otherwise falls back to ForkJoinPool.commonPool().

While @Parallel provides a convenient way to parallelise for loops, using the *Parallel collection methods (e.g. collectParallel, eachParallel) directly may offer a better debugging experience, as @Parallel performs internal variable renaming in its generated code.

Since:

6.0.0
