Parameters
Name	Description
`begin`	`T &&`
`end`	`U &&`
`typename T`
`typename U`

Returns
Type	Description
`RowRange`

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 &
