Best pattern for simulating “continue” in Groovy closure

Question

It seems that Groovy does not support break and continue from within a closure. What is the best way to simulate this?

Answer 1

With rx-java you can transform an iterable in to an observable.

Then you can replace continue with a filter and break with takeWhile

Here is an example:

import rx.Observable

Observable.from(1..100000000000000000)
          .filter { it % 2 != 1} 
          .takeWhile { it<10 } 
          .forEach {println it}
