09/06/2017, 10:20 PMmap.flatMap { (key, values) -> values.map { key to it } }➕ 5❤️ 1 - j
jw
09/06/2017, 10:21 PMthere's probably some helper in stdlib that might shorten it up, but starting with map/flatMap is always easiest (for me) - d

Why is kotlin telling me this is not an Int?val foo: Int = 0xFFFFFFFF - j
jw
09/06/2017, 11:07 PMbecause literals are signed - j
jw
09/06/2017, 11:08 PMyou don't write signed numbers in hex? - j
jw
09/06/2017, 11:09 PM(and thus you're overflowing
with that "large" number)Int - j
jw
09/06/2017, 11:09 PMit makes no sense. you have to calltoLong() - g

09/06/2017, 11:36 PMI just stumbled across this syntax for a synchronized val getter. Strangely, it doesn't seem to be documented anywhere. is
preferred?@Synchronized get()Copy code@get:Synchronized val things: List<Thing> get() = thingMap.values.toList() - j

09/06/2017, 11:39 PM😮 thanks jw! - j

is preferred, in my opinion. Use@Synchronized get
when you don't have a@get
function to hang annotations off ofget👍 3 - j

09/07/2017, 1:07 AMhey guys, is there an easy alternative to destructuring a list into 6 fields? I originally had a List<String> being destructured into 5 fields, but now I need to add one more and apparently List<String> doesn't have a component6() function - j
jelloranger
09/07/2017, 1:08 AMIs the cleanest alternative to just declare each field one by one based on position in the list now? - j
jelloranger
09/07/2017, 1:18 AMi.e. I have
and want to add a string6, but it looks like I'll have to break it up into 6 individual lines now, i.e.val (string1, string2, string3, string4, string5) = listOfStrings
etcval string1 = listOfStrings[0] - j
jw
09/07/2017, 1:20 AMsearch "component" on https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/index.html - j
jw
09/07/2017, 1:20 AMyou'll see there's only 5 defined - j
jw
09/07/2017, 1:21 AMyou can probably add your own
to make it work?fun <T> List<T>.component6() = this[5] - j
jelloranger
09/07/2017, 1:24 AMah, I didn't think of adding an extension method. Sounds like it'll work, thanks! - j
jelloranger
09/07/2017, 1:30 AMhad to add the operator keyword in the front, but it works - j
jw
09/07/2017, 1:31 AMinteresting. good to know. - h
