Classes
KeyRange
KeyRange(start_open=None, start_closed=None, end_open=None, end_closed=None)Identify range of table rows via start / end points.
Specify either a start_open or start_closed key, or defaults to
start_closed = []. Specify either an end_open or end_closed key,
or defaults to end_closed = []. However, at least one key has to be
specified. If no keys are specified, ValueError is raised.

end_open |
list of scalars
keys identifying end of range (this key excluded) |
end_closed |
list of scalars
keys identifying end of range (this key included) |
| Exceptions | |
