xrootdlib.streams.XrdXrootdMon.utility module¶

class PSeq(pseq: int)¶

Bases: object

Sortable Packet Sequence, an Integer from a wrapping (0, 255) range

Parameters:	pseq – the `pseq` of a packet

This represents the XRootD Packet Sequence for the purpose of comparisons. It ensures that comparisons respects wrapping from 255 to 0. In effect, a high-valued PSeq compares less than a low-valued PSeq.

Warning:	This class does not implement a full Integer interface.

exception PacketBufferExhausted¶

Bases: Exception

The buffer of packet data is exhausted

packet_from_buffer(packet_source: IO[bytes])¶: Read a packet from a bytes buffer
