Class RowSet (2.20.0)

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.

Constructors

RowSet()

Create an empty set.

RowSet(RowSet &&)

Parameter
Name	Description
	`RowSet &&`

RowSet(RowSet const &)

Parameter
Name	Description
	`RowSet const &`

RowSet(Arg &&...)

Parameters
Name	Description
`a`	`Arg &&...`
`typename...`

Operators

operator=(RowSet &&)

Parameter
Name	Description
	`RowSet &&`

Returns
Type	Description
`RowSet &`

operator=(RowSet const &)

Parameter
Name	Description
	`RowSet const &`

Returns
Type	Description
`RowSet &`

Functions

Append(RowRange)

Add range to the set.

Parameter
Name	Description
`range`	`RowRange`

Returns
Type	Description
`void`

Append(T &&)

Add row_key to the set, minimize copies when possible.

Parameters
Name	Description
`row_key`	`T &&`
`typename T`

Returns
Type	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
Name	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.

Returns
Type	Description
`bool`

as_proto() const &

Returns
Type	Description
`::google::bigtable::v2::RowSet const &`

as_proto() &&

Returns
Type	Description
`::google::bigtable::v2::RowSet &&`
