Protected Methods

Method	Description
ChooseServerInstance ( ConnectedInstanceCollection connectedInstances, ReadPreference readPreference ) : MongoServerInstance	Chooses the server instance.
DetermineServerState ( MongoServerState currentState, IEnumerable instances ) : MongoServerState	Determines the state of the server.
EnsureInstanceWithAddress ( MongoServerAddress address ) : void	Ensures that an instance with the address exists.
IsValidInstance ( MongoServerInstance instance ) : bool	Determines whether the instance is a valid. If not, the instance is removed.
MakeInstancesMatchAddresses ( IEnumerable addresses ) : void	Ensures that the current instance list has all the addresses provided and does not contain any not provided.
