Method Detail

copy

public static byte[] copy(byte[] bytes)

toHex

public static java.lang.String toHex(byte[] bytes)

Parameters:

bytes - Bytes to encode

fromHex

public static byte[] fromHex(java.lang.String hex)

Parameters:

hex - String of hexadecimal digits to decode as bytes.

singleFromHex

public static byte singleFromHex(java.lang.String hex)

Parse a single byte from two hexadecimal characters.

Parameters:

hex - String of hexadecimal digits to decode as bytes.

getUint8

public static short getUint8(byte b)

Read one byte as an unsigned 8-bit integer.

Result is of type Short because Java don't have unsigned types.

Returns:

A value between 0 and 255, inclusive.

getUint16

public static int getUint16(byte[] bytes)

Read 2 bytes as a big endian unsigned 16-bit integer.

Result is of type Int because Java don't have unsigned types.

Returns:

A value between 0 and 2^16- 1, inclusive.

getUint32

public static long getUint32(byte[] bytes)

Read 4 bytes as a big endian unsigned 32-bit integer.

Result is of type Long because Java don't have unsigned types.

Returns:

A value between 0 and 2^32 - 1, inclusive.

encodeUint16

public static byte[] encodeUint16(int value)
