IsEmpty() const

Return true if the range is empty.

Note that some ranges (such as ["", ""]) are not empty but only include invalid row keys.

Returns
Type Description
bool

Contains(T const &) const

Return true if key is in the range.

Parameters
Name Description
key T const &
typename T
Returns
Type Description
bool

Intersect(RowRange const &) const

Compute the intersection against another RowRange.

Parameter
Name Description
range RowRange const &
Returns
Type Description
std::pair< bool, RowRange >

a 2-tuple, the first element is a boolean, with value true if there is some intersection, the second element is the intersection. If there is no intersection the first element is false and the second element has a valid, but unspecified value.

as_proto() const &
