| public static java.lang.String | getHostAddress(int address)Returns 32-bit integer address to IPv4 address string "%d.%d.%d.%d" format.
return ((address >>> 24) & 0xFF) + "." +
((address >>> 16) & 0xFF) + "." +
((address >>> 8) & 0xFF) + "." +
((address >>> 0) & 0xFF);

| public static java.lang.String | getModeName(int mode)Return human-readable name of message mode type (RFC 1305).

| public static java.lang.String | getRefAddress(NtpV3Packet packet)Returns NTP packet reference identifier as IP address.
int address = (packet == null) ? 0 : packet.getReferenceId();
return getHostAddress(address);
|
| public static java.lang.String | getReferenceClock(NtpV3Packet message)Get refId as reference clock string (e.g. GPS, WWV, LCL). If string is
invalid (non-ASCII character) then returns empty string "".
For details refer to the Comprehensive
List of Clock Drivers.
if (message == null)
return "";
int refId = message.getReferenceId();
if (refId == 0)
return "";
StringBuffer buf = new StringBuffer(4);
// start at highest-order byte (0x4c434c00 -> LCL)
for (int shiftBits = 24; shiftBits >= 0; shiftBits -= 8)
{
char c = (char) ((refId >>> shiftBits) & 0xff);
if (c == 0) break; // 0-terminated ASCII string
if (!Character.isLetterOrDigit(c))
return "";
buf.append(c);
}
return buf.toString();
