pack method Null safety

String pack()

Encodes this HLC into a string representation whose topological ordering is equivalent to that of the original HLC.

Implementation

String pack() {
  final buffer = StringBuffer();
  buffer.write(timestamp.toString().padLeft(15, '0'));
  buffer.write(delimiter);
  buffer.write(count.toRadixString(36).padLeft(5, '0'));
  buffer.write(delimiter);
  buffer.write(node);
  return buffer.toString();
}
