预定义常量

MongoDB\Driver\Server::TYPE_UNKNOWN

Unknown server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_STANDALONE

Standalone server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_MONGOS

Mongos server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_POSSIBLE_PRIMARY

Replica set possible primary server type, returned by MongoDB\Driver\Server::getType().

A server may be identified as a possible primary if it has not yet been checked but another memory of the replica set thinks it is the primary.

MongoDB\Driver\Server::TYPE_RS_PRIMARY

Replica set primary server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_RS_SECONDARY

Replica set secondary server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_RS_ARBITER

Replica set arbiter server type, returned by MongoDB\Driver\Server::getType().

MongoDB\Driver\Server::TYPE_RS_OTHER

Replica set other server type, returned by MongoDB\Driver\Server::getType().

Such servers may be hidden, starting up, or recovering. They cannot be queried, but their hosts lists are useful for discovering the current replica set configuration.

MongoDB\Driver\Server::TYPE_RS_GHOST

Replica set ghost server type, returned by MongoDB\Driver\Server::getType().

Servers may be identified as such in at least three situations: briefly during server startup; in an uninitialized replica set; or when the server is shunned (i.e. removed from the replica set config). They cannot be queried, nor can their host list be used to discover the current replica set configuration; however, the client may monitor this server in hope that it transitions to a more useful state.
