void TelemetryLogger::telem_rcvd ( u32  key, const QCBORItem &  item, QCBORDecodeContext *  cbor  )

overrideprotectedvirtual

Callback for each received key/value pair.

The child object MUST override this callback method. Users with string keys should compare against the hash first, to ensure the matching process can iterate quickly.

Parameters

key	Integer key, or CRC32 hash of a string key.
item	Value associated with this key.
cbor	QCBOR decoder for reading complex data structures. This pointer is provided for maps and arrays, not for simple items. The callback MUST NOT call ExitArray or ExitMap.

Implements satcat5::net::TelemetryWatcher.
