# Array Runtime Support
1

2
Array cloning utilities supporting all primitive array types and object arrays with proper type preservation. The ArrayRuntime object provides essential array operations for the Scala Native runtime system.

### Array Cloning
13

14
Creates shallow copies of arrays for all primitive types and object arrays.
15

16
```scala { .api }
17
object ArrayRuntime {
18
  def cloneArray(array: Array[Boolean]): Array[Boolean]
19
  def cloneArray(array: Array[Byte]): Array[Byte]
20
  def cloneArray(array: Array[Short]): Array[Short]
21
  def cloneArray(array: Array[Char]): Array[Char]
22
  def cloneArray(array: Array[Int]): Array[Int]
23
  def cloneArray(array: Array[Long]): Array[Long]
24
  def cloneArray(array: Array[Float]): Array[Float]
25
  def cloneArray(array: Array[Double]): Array[Double]
26
  def cloneArray(array: Array[java.lang.Object]): Array[java.lang.Object]
27
}
28
```

## Usage Examples
31

32
```scala
33
import scala.runtime.ArrayRuntime
34

35
// Clone primitive arrays
36
val intArray = Array(1, 2, 3, 4, 5)
37
val clonedIntArray = ArrayRuntime.cloneArray(intArray)
38

39
val doubleArray = Array(1.0, 2.0, 3.0)
40
val clonedDoubleArray = ArrayRuntime.cloneArray(doubleArray)
41

42
// Clone object arrays
43
val stringArray = Array("hello", "world")
44
val clonedStringArray = ArrayRuntime.cloneArray(stringArray.asInstanceOf[Array[java.lang.Object]])
45

46
// The cloned arrays are independent
47
clonedIntArray(0) = 100
48
println(intArray(0))       // 1 (original unchanged)
49
println(clonedIntArray(0)) // 100 (clone modified)
50
```

## Notes
53

54
- All `cloneArray` methods perform shallow copying
55
- For object arrays, only the array container is cloned, not the contained objects
56
- The cloned arrays are completely independent of the original arrays
57
- Type preservation is maintained through method overloading
