collection.fill( )
collection.fill( )
The collection.fill( ) method fills the collection with the specified value, optionally from startFrom index to end index, and returns the resulting collection.
Note: This method modifies the original collection.
- If the startFrom parameter is omitted, value is set to all collection elements (startFrom=0). If the end parameter is omitted, the value is set to the last element of the collection (end=length).
- If startFrom < 0, it is recalculated as startFrom:=startFrom+length (it is considered as the offset from the end of the collection). If the calculated value is negative, startFrom is set to 0.
- If end < 0 , it is recalculated as end:=end+length.
- If end < startFrom (passed or calculated values), the method does nothing.
C_COLLECTION($c)
$c:=New collection(1;2;3;"Lemon";Null;"";4;5)
$c.fill("2") // $c:=[2,2,2,2,2,2,2,2]
$c.fill("Hello";5) // $c=[2,2,2,2,2,Hello,Hello,Hello]
$c.fill(0;1;5) // $c=[2,0,0,0,0,Hello,Hello,Hello]
$c.fill("world";1;-5) //-5+8=3 -> $c=[2,"world","world",0,0,Hello,Hello,Hello]
