The MongoDB\Driver\WriteConcern class

(mongodb >=1.0.0)


MongoDB\Driver\WriteConcern describes the level of acknowledgement requested from MongoDB for write operations to a standalone mongod or to replica sets or to sharded clusters. In sharded clusters, mongos instances will pass the write concern on to the shards.


final class MongoDB\Driver\WriteConcern implements MongoDB\BSON\Serializable, Serializable {
/* 常量 */
const string MAJORITY = "majority";
/* 方法 */
final public bsonSerialize(): stdClass
final public __construct(string|int $w, ?int $wtimeout = null, ?bool $journal = null)
final public getJournal(): ?bool
final public getW(): string|int|null
final public getWtimeout(): int
final public isDefault(): bool
final public serialize(): string
final public unserialize(string $data): void



Majority of all the members in the set; arbiters, non-voting members, passive members, hidden members and delayed members are all included in the definition of majority write concern.
