08/10/2017, 8:30 AMdoes this mean that Bar is an interface?, so if Bar declares "fun doSomething()", I can then do (in the foo function),body().doSomething()? - m

08/10/2017, 8:31 AMNo, it simply means that an instance of
(whatever type that is) is available asBar
inside the lambda. It's called a lambda with receiver.this➕ 1 - m
menegatti
08/10/2017, 8:31 AM"function literals with receiver" I'll never remember its name - d
dharrigan
08/10/2017, 8:33 AMokay, will read, but say I do want to invoke something on the passed in function (body() in this case) so that I can do
is that possible? (am I being clear?).body().doSomething() - d
diesieben07
08/10/2017, 8:34 AMYou would call it as
.someBarInstance.body() - d
dharrigan
08/10/2017, 8:34 AMkk, will read and try to code it out - d
diesieben07
08/10/2017, 8:34 AMAnd the lambda returns
, which does not have any (useful) methods. But in theory, yes, you can.Unit - d

that cares about the insertion order of entries.Map
does, so make sure you use that, then grab itsLinkedHashMap
and obtain the key from therekeySet() - m

08/10/2017, 11:02 AMlol, this is harder than basic - m

08/10/2017, 6:52 PMwhat’s the ideal case for a companion object? - o
oday
08/10/2017, 6:53 PMor the intended usecase - d
dalexander
08/10/2017, 6:58 PMFor when you have a singleton that’s associated with a particular class. - a
agomez
08/10/2017, 6:59 PMor static methods, for example static factory methods - o
oday
08/10/2017, 7:01 PMok - o
oday
08/10/2017, 7:12 PMif I have an
as an expression, in aifwhen - o
oday
08/10/2017, 7:12 PMI am forced to supply the
, is there a way to supply it in a pretty way instead ofelse
or am I just being nonsensically anal?else { } - d
dalexander
08/10/2017, 7:14 PMAre you assigning the result of the
to a variable? Otherwise I wouldn’t expect you would need to do that.when - k
kevinmost
08/10/2017, 7:16 PMif it's an expression, it still needs to have a type, from what I know. Your best bet isCopy codewhen(cond) { branch -> { if (otherCond) foo() } } - k
kevinmost
08/10/2017, 7:16 PM(put braces around the actual when branch's body - o
oday
08/10/2017, 7:25 PMthat’s what I have here - o
oday
08/10/2017, 7:26 PMit is assigned to a variable yes
