Intersect(bigtable::RowRange const &) const

Modify this object to contain the ranges and keys inside range.

Parameter

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.
