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
NameDescription
range bigtable::RowRange const &
Returns
TypeDescription
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.
