get_time_slide_id(self, offsetdict, create_new=None, superset_ok=False, nonunique_ok=False)

source code

Return the time_slide_id corresponding to the offset vector described by offsetdict, a dictionary of instrument/offset pairs.

If the optional create_new argument is None (the default), then the table must contain a matching offset vector. The return value is the ID of that vector. If the table does not contain a matching offset vector then KeyError is raised.

If the optional create_new argument is set to a Process object (or any other object with a process_id attribute), then if the table does not contain a matching offset vector a new one will be added to the table and marked as having been created by the given process. The return value is the ID of the (possibly newly created) matching offset vector.

If the optional superset_ok argument is False (the default) then an offset vector in the table is considered to "match" the requested offset vector only if they contain the exact same set of instruments. If the superset_ok argument is True, then an offset vector in the table is considered to match the requested offset vector as long as it provides the same offsets for the same instruments as the requested vector, even if it provides offsets for other instruments as well.

More than one offset vector in the table might match the requested vector. If the optional nonunique_ok argument is False (the default), then KeyError will be raised if more than one offset vector in the table is found to match the requested vector. If the optional nonunique_ok is True then the return value is the ID of one of the matching offset vectors selected at random.
