Method Detail

byteToInt

public static int[] byteToInt(byte[] arr)

Convert the given byte array to an array of ints. The bytes are assumed to actually represent int values in the range 0..255, and so have 128 added to each value.

Parameters:

arr - the byte array

Returns:

an array of ints

byteToInt

public static int[][] byteToInt(byte[][] arr)

Convert the given 2d byte array to a 2d array of ints. The bytes are assumed to actually represent int values in the range 0..255, and so have 128 added to each value.

Parameters:

arr - the byte array

Returns:

an array of ints

intToByte

public static byte[] intToByte(int[] arr)

Convert the given int array to an array of bytes. The ints are assumed to be in the range 0..255, and so 128 is subtracted before casting to a byte.

Parameters:

arr - the int array

Returns:

an array of bytes

intToByte

public static byte[][] intToByte(int[][] arr)

Convert the given 2d int array to a 2d array of bytes. The ints are assumed to be in the range 0..255, and so 128 is subtracted before casting to a byte.

Parameters:

arr - the int array

Returns:

an array of bytes
