Member Function Documentation

durability_level() [1/2]

auto durability_level ( ) const -> std::optional< couchbase::durability_level >

nodiscard

Get the durability if it has been set.

See also

couchbase::durability_level for details.

Returns

durability if set.

durability_level() [2/2]

auto durability_level

(

durability_level

level

)

-> transaction_options &

Set durability for this transaction.

See also

couchbase::durability_level for details.

Parameters

level

Durability level for this transaction.

Returns

reference to this object, convenient for chaining operations.

metadata_collection() [1/3]

auto metadata_collection ( ) const -> std::optional< transaction_keyspace >

nodiscard

Get the metadata collection, if set.

Returns

the metadata collection, as a transaction_keyspace, if set.

metadata_collection() [2/3]

auto metadata_collection

(

const couchbase::collection &

coll

)

-> transaction_options &

Set the metadata collection to use for this transaction.

Transactions involve a the creation and use of some metadata documents, which by default are placed in the default collection of scope which the first document in the that has a mutating operation performed on it. However, you can set this to a specific collection to isolate these documents from your documents, if desired.

Parameters

coll	The desired collection to use.

Returns

reference to this object, convenient for chaining operations.

metadata_collection() [3/3]

auto metadata_collection ( const couchbase::transactions::transaction_keyspace & keyspace ) -> transaction_options &

inline

Set metadata collection to use for this transaction.

Parameters

keyspace

The desired collection to use

Returns

reference to this object, convenient for chaining operations.

scan_consistency() [1/2]

auto scan_consistency ( ) const -> std::optional< query_scan_consistency >

nodiscard

Get the scan_consistency if it has been set.

See also

query_options::scan_consistency for details.

Returns

The scan_consistency, if set.

scan_consistency() [2/2]

auto scan_consistency

(

query_scan_consistency

scan_consistency

)

-> transaction_options &

Set the query_scan_consistency for this transaction.

See also

query_options::scan_consistency for details.

Parameters

scan_consistency

The desired query_scan_consistency for this transaction.

Returns

reference to this object, convenient for chaining operations.

timeout() [1/2]

auto timeout

(

)

-> std::optional< std::chrono::nanoseconds >

Get the timeout, if set.

Returns

the timeout, if set.

timeout() [2/2]

template<typename T>

auto timeout ( T timeout ) -> transaction_options &

inline

Set the timeout for this transaction.

Template Parameters

T	timeout type, e.g. std::chrono::milliseconds, or similar

Parameters

timeout

Desired timeout

Returns

reference to this object, convenient for chaining operations.
