Method Detail

encodeFloat

public static byte[] encodeFloat(float payload)

encodeFloat

public static byte[] encodeFloat(float payload,
                                 byte[] data,
                                 int offset)

encodeInt

public static byte[] encodeInt(int payload)

encodeInt

public static byte[] encodeInt(int payload,
                               byte[] data,
                               int offset)

decodeFloat

public static float decodeFloat(byte[] bytes)
Parameters:
bytes -
Returns:
the decoded float
See Also:
decodeFloat(byte[], int), encodeFloat(float)

decodeFloat

public static final float decodeFloat(byte[] bytes,
                                      int offset)
Decode the payload that was encoded using encodeFloat(float). NOTE: the length of the array must be at least offset + 4 long.

Parameters:
bytes - The bytes to decode
offset - The offset into the array.
Returns:
The float that was encoded
See Also:
encodeFloat(float)

decodeInt

public static final int decodeInt(byte[] bytes,
                                  int offset)
