Fields

connected

This property will be set to TRUE if we have a open connection to the database, FALSE otherwise. If the connection is to a replica set, this property will only be TRUE if the driver has a connection to a node matching the current read preference. This property does not take authentication into account.

This property is deprecated since version 1.5.0.

status

This property is no longer used and will be set to NULL In driver versions 1.1.x and earlier, this may be set to a string value (e.g. "recycled", "new") when persistent connections are used.

This property is deprecated since version 1.5.0.
