Method Detail

• intArraySet

  public static void intArraySet(int[] arr,
                                 int val)

  Reinitializes an int array to the given value in an optimized way. If the length of the array is less than MAX_EL_COPYING, then the array is set element by element in the normal way, otherwise the first INIT_EL_COPYING elements are set element by element and then System.arraycopy is used to set the other parts of the array.

  Parameters:

  arr - The array to set.

  val - The value to set the array to.

• byteArraySet

  public static void byteArraySet(byte[] arr,
                                  byte val)

  Reinitializes a byte array to the given value in an optimized way. If the length of the array is less than MAX_EL_COPYING, then the array is set element by element in the normal way, otherwise the first INIT_EL_COPYING elements are set element by element and then System.arraycopy is used to set the other parts of the array.

  Parameters:

  arr - The array to set.

  val - The value to set the array to.
