Copy code

class Foo(val nrow:Int){
val rowNumber: Iterable<Int> get() = 1..nrow

val rowNumber: Iterable<Int>  by lazy { (1..nrow) }
}

The

lazy

will cache the result in a backing field, but the first impl using

get

won’t, is this correct? If so, should I prefer

lazy

impl if the operation might be expensive and the

rowNumber

would be accessed multiple times?
