Detailed Description

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.

Constructor & Destructor Documentation

RowSet() [1/4]

google::cloud::bigtable::RowSet::RowSet ( )

default

Create an empty set.

RowSet() [2/4]

google::cloud::bigtable::RowSet::RowSet ( RowSet &&  )

default

RowSet() [3/4]

google::cloud::bigtable::RowSet::RowSet ( RowSet const &  )

default

RowSet() [4/4]

template<typename... Arg>

google::cloud::bigtable::RowSet::RowSet ( Arg &&...  a )

inline

Member Function Documentation

Append() [1/2]

void google::cloud::bigtable::RowSet::Append ( RowRange  range )

inline

Add range to the set.

Append() [2/2]

template<typename T >

void google::cloud::bigtable::RowSet::Append ( T &&  row_key )

inline

Add row_key to the set, minimize copies when possible.

as_proto() [1/2]

::google::bigtable::v2::RowSet && google::cloud::bigtable::RowSet::as_proto ( ) &&

inline

as_proto() [2/2]

::google::bigtable::v2::RowSet const & google::cloud::bigtable::RowSet::as_proto ( ) const &

inline

Intersect()

RowSet google::cloud::bigtable::RowSet::Intersect

(

bigtable::RowRange const &

range

)

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.

IsEmpty()

bool google::cloud::bigtable::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.

operator=() [1/2]

RowSet & google::cloud::bigtable::RowSet::operator= ( RowSet &&  )

default

operator=() [2/2]

RowSet & google::cloud::bigtable::RowSet::operator= ( RowSet const &  )

default
