inline val Long.sign
get() = when {
this > 0L -> 1
this < 0L -> -1
else -> 0
}
inline val Long.abs
get() = Math.abs(this)karelpeeters

08/21/2017, 1:47 PMGood. Thanks Karel. I try find some example using property extension with var. Maybe i will back to StringBuffer property extension, is more simple to understand.

08/21/2017, 1:50 PM@karelpeeters I use them for specialized dictionaries:
Copy code
inline var Map<String, MyKey>.isStarted: Boolean
get() = this["isStarted"].booleanValue
set(newValue: Boolean) = this["isStarted"] = MyKey(booleanValue = newValue)2 Views
