Parameters:

source - The long value to be translated.

Returns:

Byte array representation of the bypassed long value.

byteArrayToLong

public static long byteArrayToLong(byte[] byteArray)

Converts the bypassed byte array to a long value.

Parameters:

byteArray - The byte array to be translated.

Returns:

"long" representation of the bypassed byte array.

intToByteArray

public static byte[] intToByteArray(int source)

Converts the bypassed int value to a byte array.

Parameters:

source - The int value to be translated.

Returns:

Byte array representation of the bypassed int value.

byteArrayToInt

public static int byteArrayToInt(byte[] byteArray)

Converts the bypassed byte array to an int value.

Parameters:

byteArray - The byte array to be translated.

Returns:

"int" representation of the bypassed byte array.

shortToByteArray

public static byte[] shortToByteArray(int source)

Converts the bypassed short value to a byte array.

Parameters:

source - The short value to be translated.

Returns:

Byte array representation of the bypassed short value.

byteArrayToShort

public static int byteArrayToShort(byte[] byteArray)

Converts the bypassed byte array to a short value.

Parameters:

byteArray - The byte array to be translated.

Returns:

mergeArrays

public static byte[] mergeArrays(byte[] firstArray,
                                 byte[] secondArray)

Merges the bypassed byte arrays (secondArray is appended to firstArray).

Parameters:

firstArray - Array to be extended.

secondArray - Array to be appended.

Returns:

Merged array.
