Method Detail

fromString

public static long[] fromString(CharSequence chars)

Returns the long value.

Parameters:

chars - the base8 or base16 representation of the long.

Returns:

long array from string. Either contains high and low or just low trace id

longFromBase16String

public static long longFromBase16String(CharSequence chars)

Returns the long value whose base16 representation is stored in the first 16 chars of chars starting from the offset.

Parameters:

chars - the base16 representation of the long.

Returns:

long value from string

byteFromBase16String

public static byte byteFromBase16String(CharSequence chars,
                                        int offset)

Decodes the specified two character sequence, and returns the resulting byte.

Parameters:

chars - the character sequence to be decoded.

offset - the starting offset in the CharSequence.

Returns:

the resulting byte

Throws:

IllegalArgumentException - if the input is not a valid encoded string according to this encoding.

isValidBase16String

public static boolean isValidBase16String(CharSequence value)

Checks if string is valid base16.

Parameters:

value - to check

Returns:

true if valid base16 string

fromLong

public static String fromLong(long id)

Converts long into string.

Parameters:

id - 64 bit

Returns:

string representation of the long

fromLongs

public static String fromLongs(long idHigh,
                               long idLow)

Converts longs into string.

Parameters:

idHigh - - trace id high part

idLow - - trace id low part

Returns:

string representation of the long

longToBase16String

public static void longToBase16String(long value,
                                      char[] dest,
                                      int destOffset)

byteToBase16

public static void byteToBase16(byte value,
                                char[] dest,
                                int destOffset)
