copyToArray
trait Collection[A] {
def copyToArray[B :> A](array: Array[B]): Int
def copyToArray[B :> A](array: Array[B], i: Int): Int
def copyToArray[B :> A](array: Array[B], i: Int, l: Int): Int
}
copyToArray
copies elements from this collection to an Array
and returns
how many elements were copied.
The copy can be placed in the target Array
at a given offset i
.
Also the copy can be restricted to, as much, the first l
elements.
In any case, those elements exceeding the bounds of the Array
will be discarded.
