class sbp.client.loggers.json_logger.JSONBinLogger(handle, tags={}, dispatcher=None)

Bases: sbp.client.loggers.base_logger.BaseLogger

The JSONLogger logs JSON records without expanding the fields.

class sbp.client.loggers.json_logger.JSONLogIterator(handle, dispatcher=<function dispatch>)

Bases: sbp.client.loggers.base_logger.LogIterator

The JSONLogIterator is an iterator for reading JSON logs of SBP data.

filename

: string

Path to file to read SBP messages from.

next()

Return the next record tuple from log file containing JSON-serialized SBP. If an unknown SBP message type is found, it’ll return the raw SBP. If EOF, throws exception and then returns to start of file.

Tuple(sbp MSG object, {‘time’:’ISO 8601 time’})

Second item is for metadata. There used to be multiple fields and there could be more in the future.

In practice it seems like a lot of times JSONLogIterator objects return iterators instead of tuples due to weird usage of the class.
