function that has this signature: ```with - b

08/03/2017, 8:04 PMAbout the `with`function that has this signature:Copy code
concerninginline fun <T, R> with(receiver: T, block: T.() -> R): R
parameter, is it true to say that it is an anonymous extension function on T type that takes no parameter and returns a reference of type R?block - k

08/03/2017, 8:17 PMI wouldn't say it's an anonymous function. it's a instance of an extension function type, commonly called "extension lambda" - b

08/03/2017, 9:02 PMhow can I do it - o
oscarg798
08/03/2017, 9:02 PMas String on kotlin does not have insert method - o
oscarg798
08/03/2017, 9:06 PMfound the solution I will convert string to editable - o
oscarg798

08/03/2017, 9:13 PMHello. I’m working with Realm and facing the problem with
methodremove(int position)
overridesclass RealmList<E extends RealmModel> extends AbstractList<E> implements OrderedRealmCollection<E>
method frompublic E remove(int index)
When I’m trying to call it from kotlin I get compilation error asAbstractList
method resolves toremove
where it is deprecated with Error levelMutableCollections.ktCopy code
Is this a bug and is there any workaround for the issue?val list = RealmList<Smth>() list.remove(0) Error:(31, 19) Using 'remove(Int): T' is an error. Use removeAt(index) instead. - a

08/04/2017, 1:13 AMSo... is it crazy to have a function return null just to be able to use the elvis operator on the result? - j

08/04/2017, 1:14 AMno - d
dumptruckman
08/04/2017, 1:14 AM(where the alternative return would be nothing of value) - j
jw
08/04/2017, 1:14 AMnull doesn't need to be avoided, it just needs to be explicitly represented such that handling it is forced - d
dumptruckman
08/04/2017, 1:15 AMlike... it would either return true or null - d
dumptruckman
08/04/2017, 1:15 AMbut true has no value to the function caller - d
dumptruckman
08/04/2017, 1:15 AMit just feels wrong - j
