is it possible to break out of closure in groovy

Question

is there a way to \'break\' out of a groovy closure.

maybe something like this:

[1, 2, 3].each { 
  println(it)
  if (it == 2)
    break 
}
<         


        

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}
