isNullOrEmpty()g

09/14/2018, 2:26 AMso that they can be overloadedI didn’t get what you mean.

Hullaballoonatic
09/14/2018, 2:27 AMi mean are they functions and not properties so that users can overload the function? it was a guess of mine
g
gildor
09/14/2018, 2:27 AMOverload?
gildor
09/14/2018, 2:27 AMDo you mean override?
h
Hullaballoonatic
09/14/2018, 2:27 AMyeah sorry!
g
gildor
09/14/2018, 2:27 AM“Overload” term usually applied to math operators
h
Hullaballoonatic
09/14/2018, 2:28 AMyou're absolutely right
g
gildor
09/14/2018, 2:28 AMThere is no difference between function and property in terms of overriding rules
gildor
09/14/2018, 2:29 AMAnd I still don’t understand what do you mean.
You cannot override extension function/property.
The only what you can do is add member function/property to class, such member will have higher priority than extension function

09/14/2018, 2:29 AMokay so i believe my question stands, then... why not omit the
()g
gildor
09/14/2018, 2:30 AMThere is no very strict answer in this.
Style guide has some attempts to distinguish between those cases, but not sure that they are applied in this case for property or for function choice

09/14/2018, 2:30 AMi'll try to be clearer; i write the following into many of my programs:
Copy code
val Collection.isNotEmpty get() = !this.isEmpty()Hullaballoonatic
09/14/2018, 2:31 AMjust because i think it looks and reads better

09/14/2018, 2:32 AMlist.isNotEmptylist.isNotEmpty()gildor
09/14/2018, 2:32 AMbut I don’t see nothing wrong to use propery in this case
gildor
09/14/2018, 2:33 AMJust stdlib uses usually extension functions instead of extension properties
h
Hullaballoonatic
09/14/2018, 2:33 AMidk, i just always feel like less is more, and if the () are not needed for any purpose, i wanna drop them 😮
g
gildor
09/14/2018, 2:33 AMone more reason for that probably because inline extension functions supported from the beginning, but inline properties added only in Kotlin 1.1

09/14/2018, 2:34 AMrighto. lots of exciting stuff coming in 1.3!
