Represent a (possibly non-continuous) set of row keys.
Cloud Bigtable can scan non-continuous sets of rows, these sets can include a mix of specific row keys and ranges as defined by bigtable::RowRange.

Description
void
Intersect(bigtable::RowRange const &) const
Modify this object to contain the ranges and keys inside range.
This function removes any rowkeys outside range, it removes any row ranges that do not intersect with range, and keeps only the intersection for those ranges that do intersect range.
Parameter

Description
range
bigtable::RowRange const &
Returns
Type
Description
RowSet
IsEmpty() const
Returns true if the set is empty.
A row set is empty iff passing it to a ReadRows call would never cause it to return rows. This is true if the set consists of only empty ranges.
Note that a default constructed RowSet is not empty, since it matches all rows in the table.
