IsoTpReceptionInProgress Class¶
A multi-frame reception that has begun and not completed: the First Frame's arrival, the length it announced, and the data bytes it carried (see GetReceptionsInProgress()).
Inheritance Object → IsoTpReceptionInProgress
Remarks¶
Published when the First Frame is read off the bus, before the channel's protocol actor has accepted it — so a caller whose deadline fires while the actor is still behind sees the frame at its arrival, not at its processing. Several can be pending when the actor is behind: a PDU whose frames all sit in the mailbox is still in progress when the next First Frame is read. The actor withdraws a record on its outcome — the PDU or the abort in the inbox — or when it refuses the frame (a short First Frame, or one announcing more than the channel accepts), so a record is not a promise that the PDU will be delivered; a caller waiting on one re-checks rather than waiting unboundedly.
Constructors¶
IsoTpReceptionInProgress(long, int, ReadOnlyMemory<byte>) Constructor¶
Creates a record; the channel is the only intended caller.
public IsoTpReceptionInProgress(long firstFrameArrivalTimestamp, int announcedLength, System.ReadOnlyMemory<byte> firstFrameData);
Parameters¶
firstFrameArrivalTimestamp Int64
announcedLength Int32
firstFrameData ReadOnlyMemory<Byte>
Properties¶
IsoTpReceptionInProgress.AnnouncedLength Property¶
The PDU length the First Frame announced.
Property Value¶
IsoTpReceptionInProgress.FirstFrameArrivalTimestamp Property¶
When the First Frame arrived, as a GetTimestamp reading on the same clock as ArrivalTimestamp.
Property Value¶
IsoTpReceptionInProgress.FirstFrameData Property¶
The PDU's leading bytes as the First Frame carried them — enough for an application layer to tell whose response this is (a UDS response SID is the first byte).
