/**
 * Takes a row as input and produces an alternate view of the row based on
 * specified rules. For example, a RowFilter might trim down a row to include
 * just the cells from columns matching a given regular expression, or might
 * return all the cells of a row but not their values. More complicated filters
 * can be composed out of these components to express requests such as, "within
 * every column of a particular family, give just the two most recent cells
 * which are older than timestamp X."
 * There are two broad categories of RowFilters (true filters and transformers),
 * as well as two ways to compose simple filters into more complex ones
 * (chains and interleaves). They work as follows:
 * * True filters alter the input row by excluding some of its cells wholesale
 * from the output row. An example of a true filter is the `value_regex_filter`,
 * which excludes cells whose values don't match the specified pattern. All
 * regex true filters use RE2 syntax (https://github.com/google/re2/wiki/Syntax)
 * in raw byte mode (RE2::Latin1), and are evaluated as full matches. An
 * important point to keep in mind is that `RE2(.)` is equivalent by default to
 * `RE2([^\n])`, meaning that it does not match newlines. When attempting to
 * match an arbitrary byte, you should therefore use the escape sequence `\C`,
 * which may need to be further escaped as `\\C` in your client language.
 * * Transformers alter the input row by changing the values of some of its
 * cells in the output, without excluding them completely. Currently, the only
 * supported transformer is the `strip_value_transformer`, which replaces every
 * cell's value with the empty string.
 * * Chains and interleaves are described in more detail in the
 * RowFilter.Chain and RowFilter.Interleave documentation.
 * The total serialized size of a RowFilter message must not
 * exceed 4096 bytes, and RowFilters may not be nested within each other
 * (in Chains or Interleaves) to a depth of more than 20.

     *           As with an [Interleave][google.bigtable.v2.RowFilter.Interleave],
     *           duplicate cells are possible, and appear in an unspecified mutual order.
     *           In this case we have a duplicate with column "A:B" and timestamp 2,

     *           passed through the label and sink. Note that one copy has label "foo",
     *           while the other does not.
     *           Cannot be used within the `predicate_filter`, `true_filter`, or
     *           `false_filter` of a [Condition][google.bigtable.v2.RowFilter.Condition].
     *     @type bool $pass_all_filter
     *           Matches all cells, regardless of input. Functionally equivalent to
     *           leaving `filter` unset, but included for completeness.
     *     @type bool $block_all_filter
     *           Does not match any cells, regardless of input. Useful for temporarily
     *           disabling just part of a filter.
     *     @type string $row_key_regex_filter
     *           Matches only cells from rows whose keys satisfy the given RE2 regex. In
     *           other words, passes through the entire row when the key matches, and
     *           otherwise produces an empty row.
     *           Note that, since row keys can contain arbitrary bytes, the `\C` escape
     *           sequence must be used if a true wildcard is desired. The `.` character
     *           will not match the new line character `\n`, which may be present in a
     *           binary key.
     *     @type float $row_sample_filter
     *           Matches all cells from a row with probability p, and matches no cells
     *           from the row with probability 1-p.
     *     @type string $family_name_regex_filter
     *           Matches only cells from columns whose families satisfy the given RE2
     *           regex. For technical reasons, the regex must not contain the `:`
     *           character, even if it is not being used as a literal.
     *           Note that, since column families cannot contain the new line character
     *           `\n`, it is sufficient to use `.` as a full wildcard when matching
     *           column family names.
     *     @type string $column_qualifier_regex_filter
     *           Matches only cells from columns whose qualifiers satisfy the given RE2
     *           regex.
     *           Note that, since column qualifiers can contain arbitrary bytes, the `\C`
     *           escape sequence must be used if a true wildcard is desired. The `.`
     *           character will not match the new line character `\n`, which may be
     *           present in a binary qualifier.
     *     @type \Google\Cloud\Bigtable\V2\ColumnRange $column_range_filter
     *           Matches only cells from columns within the given range.
     *     @type \Google\Cloud\Bigtable\V2\TimestampRange $timestamp_range_filter
     *           Matches only cells with timestamps within the given range.
     *     @type string $value_regex_filter
     *           Matches only cells with values that satisfy the given regular expression.
     *           Note that, since cell values can contain arbitrary bytes, the `\C` escape
     *           sequence must be used if a true wildcard is desired. The `.` character
     *           will not match the new line character `\n`, which may be present in a
     *           binary value.
     *     @type \Google\Cloud\Bigtable\V2\ValueRange $value_range_filter
     *           Matches only cells with values that fall within the given range.
     *     @type int $cells_per_row_offset_filter
     *           Skips the first N cells of each row, matching all subsequent cells.
     *           If duplicate cells are present, as is possible when using an Interleave,
     *           each copy of the cell is counted separately.
     *     @type int $cells_per_row_limit_filter
     *           Matches only the first N cells of each row.
     *           If duplicate cells are present, as is possible when using an Interleave,
     *           each copy of the cell is counted separately.
     *     @type int $cells_per_column_limit_filter
     *           Matches only the most recent N cells within each column. For example,
     *           if N=2, this filter would match column `foo:bar` at timestamps 10 and 9,
     *           skip all earlier cells in `foo:bar`, and then begin matching again in
     *           column `foo:bar2`.
     *           If duplicate cells are present, as is possible when using an Interleave,
     *           each copy of the cell is counted separately.
     *     @type bool $strip_value_transformer
     *           Replaces each cell's value with the empty string.
     *     @type string $apply_label_transformer
     *           Applies the given label to all cells in the output row. This allows
     *           the client to determine which results were produced from which part of
     *           the filter.
     *           Values must be at most 15 characters in length, and match the RE2
     *           pattern `[a-z0-9\\-]+`
     *           Due to a technical limitation, it is not currently possible to apply
     *           multiple labels to a cell. As a result, a Chain may have no more than
     *           one sub-filter which contains a `apply_label_transformer`. It is okay for
     *           an Interleave to contain multiple `apply_label_transformers`, as they
     *           will be applied to separate copies of the input. This may be relaxed in
     *           the future.
