public ByteConversionUtil()

Method Detail

fromShort

public static byte[] fromShort(short input)

Returns a byte array containing 2 network byte ordered bytes representing the given short.

Parameters:

input - An short to convert to a byte array.

Returns:

A byte array representation of an short in network byte order (i.e., big-endian order).

fromInt

public static byte[] fromInt(int input)

Returns a byte array containing 4 network byte-ordered bytes representing the given int.

Parameters:

input - An int to convert to a byte array.

Returns:

A byte array representation of an int in network byte order (i.e., big-endian order).

fromLong

public static byte[] fromLong(long input)

Returns a byte array containing 8 network byte-ordered bytes representing the given long.

Parameters:

input - The long to convert to a byte array.

Returns:

A byte array representation of a long.

toShort

public static short toShort(byte[] input)

Converts a given byte array to an short. Bytes are expected in network byte order.

Parameters:

input - A network byte-ordered representation of an short, so exactly 2 bytes are expected.

Returns:

The short value represented by the input array.

toInt

public static int toInt(byte[] input)

Converts a given byte array to an int. Bytes are expected in network byte order.

Parameters:

input - A network byte-ordered representation of an int. Must be exactly 4 bytes.

Returns:

The int value represented by the input array.

toLong

public static long toLong(byte[] input)

Converts a given byte array to a long. Bytes are expected in network byte

Parameters:

input - A network byte-ordered representation of a long. Must be exactly 8 bytes.

Returns:

The long value represented by the input array
