Class ColumnRangeFilter (1.4.0)

ColumnRangeFilter(
    column_family_id,
    start_column=None,
    end_column=None,
    inclusive_start=None,
    inclusive_end=None,
)

A row filter to restrict to a range of columns.

Both the start and end column can be included or excluded in the range. By default, we include them both, but this can be changed with optional flags.

Parameters

Name	Description
`column_family_id`	`str` The column family that contains the columns. Must be of the form `<code>_a-zA-Z0-9][-_.a-zA-Z0-9]</code>*`.
`start_column`	`bytes` The start of the range of columns. If no value is used, the backend applies no upper bound to the values.
`end_column`	`bytes` The end of the range of columns. If no value is used, the backend applies no upper bound to the values.
`inclusive_start`	`bool` Boolean indicating if the start column should be included in the range (or excluded). Defaults to :data:`True` if `start_column` is passed and no `inclusive_start` was given.
`inclusive_end`	`bool` Boolean indicating if the end column should be included in the range (or excluded). Defaults to :data:`True` if `end_column` is passed and no `inclusive_end` was given.

Methods

to_pb

to_pb()

Converts the row filter to a protobuf.

First converts to a .data_v2_pb2.ColumnRange and then uses it in the column_range_filter field.

Returns

Type	Description
`.data_v2_pb2.RowFilter`	The converted current object.
