      • from

         static long from(String s)

        Parse the span id from the given {@code String} representation of the unsigned 64 bit id.

        Parameters:
        s - String of unsigned 64 bit id

      • fromHex

         static long fromHex(String s)

        Parse the span id from the given {@code String} hex representation of the unsigned 64 bit id.

        Parameters:
        s - String in hex of unsigned 64 bit id

      • fromHex

         static long fromHex(String s, int start, int len, boolean lowerCaseOnly)

        Parse the span id from the given {@code String} hex representation of the unsigned 64 bit id.

        Parameters:
        s - String in hex of unsigned 64 bit id
        start - the start index of the hex value
        len - the len of the hex value
        lowerCaseOnly - if the allowed hex characters are lower case only

      • toString

         static String toString(long id)

        Returns the decimal string representation of the unsigned 64 bit id. The {@code String} willNOT be cached.

        Parameters:
        id - the long 64 bit id to generate a String for

      • toHexString

         static String toHexString(long id)

        Returns the no zero padded hex representation, in lower case, of the unsigned 64 bit id. Thehex {@code String} will NOT be cached.

      • toHexStringPadded

         static String toHexStringPadded(long id)

        Returns the zero padded hex representation, in lower case, of the unsigned 64 bit id. The sizewill be rounded up to 16 characters. The hex {@code String} will NOT be cached.
