You can simulate a continue using goto and labels. DECLARE done BOOLEAN; BEGIN FOR i IN 1..50 LOOP IF done THEN GOTO end_loop; END IF; <<end_loop>> — not allowed unless an executable statement follows NULL; — add NULL statement to avoid error END LOOP; — raises an error without the previous NULL END;
The use of continue in a finally-clause is forbidden because its interpretation would have been problematic. What would you do if the finally-clause were being executed because of an exception? for i in range(10): print i try: raise RuntimeError finally: continue # if the loop continues, what would happen to the exception? print i It … Read more
After searching for this exact problem, I found this book extract online. It exactly answers the question of how to skip the current iteration and jump straight to the next iteration of a repeat loop. Applescript has exit repeat, which will completely end a loop, skipping all remaining iterations. This can be useful in an … Read more
There are a lot of answers here. And it’s old, but this is for anyone coming here via google. In jQuery each function return false; is like break. just return; is like continue These will emulate the behavior of break and continue.
Either use return, as the closure basically is a method that is called with each element as parameter like def myObj = [“Hello”, “World!”, “How”, “Are”, “You”] myList.each{ myObj-> if(myObj==null){ return } println(“My Object is ” + myObj) } Or switch your pattern to def myObj = [“Hello”, “World!”, “How”, “Are”, “You”] myList.each{ myObj-> if(myObj!=null){ … Read more
Your suggestion would work, but using a Do loop might be a little more readable. This is actually an idiom in C – instead of using a goto, you can have a do { } while (0) loop with a break statement if you want to bail out of the construct early. Dim i For … Read more
for uses iter(song) to loop; you can do this in your own code and then advance the iterator inside the loop; calling iter() on the iterable again will only return the same iterable object so you can advance the iterable inside the loop with for following right along in the next iteration. Advance the iterator … Read more
$array = array(1,2,3); foreach ($array as $item){ if ($item == 2) { break; } echo $item; } outputs “1” because the loop was broken forever, before echo was able to print “2”. $array = array(1,2,3); foreach ($array as $item){ if ($item == 2) { continue; } echo $item; } outputs 13 because the second iteration … Read more
If you are trying to have your second continue apply to the foreach loop, you will have to change it from continue; to continue 2; This will instruct PHP to apply the continue statement to the second nested loop, which is the foreach loop. Otherwise, it will only apply to the for loop.
The statement is ridiculous. continue can be abused, but it often helps readability. Typical use: for (somecondition) { if (!firsttest) continue; some_provisional_work_that_is_almost_always_needed(); if (!further_tests()) continue; do_expensive_operation(); } The goal is to avoid ‘lasagna’ code, where you have deeply nested conditionals. Edited to add: Yes, this is ultimately subjective. Here’s my metric for deciding. Edited one … Read more
