Constants

NAME

The display name for the topology.

@since 2.0.0 @deprecated

Public Instance Methods

display_name() click to toggle source

Get the display name.

@example Get the display name.

ReplicaSet.display_name

@return [ String ] The display name.

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 40
def display_name
  self.class.name.gsub(/.*::/, '')
end
has_readable_server?(cluster, server_selector = nil) click to toggle source

Determine if the topology would select a readable server for the provided candidates and read preference.

@example Is a readable server present?

topology.has_readable_server?(cluster, server_selector)

@param [ Cluster ] cluster The cluster. @param [ ServerSelector ] server_selector The server

selector.

@return [ true, false ] If a readable server is present.

@since 2.4.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 76
def has_readable_server?(cluster, server_selector = nil)
  (server_selector || ServerSelector.primary).candidates(cluster).any?
end
has_writable_server?(cluster) click to toggle source

Determine if the topology would select a writable server for the provided candidates.

@example Is a writable server present?

topology.has_writable_server?(servers)

@param [ Cluster ] cluster The cluster.

@return [ true, false ] If a writable server is present.

@since 2.4.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 91
def has_writable_server?(cluster)
  cluster.servers.any?{ |server| server.primary? }
end
replica_set?() click to toggle source

A replica set topology is a replica set.

@example Is the topology a replica set?

topology.replica_set?

@return [ true ] Always true.

@since 2.0.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 103
def replica_set?; true; end
servers(servers) click to toggle source

Select appropriate servers for this topology.

@example Select the servers.

ReplicaSet.servers(servers)

@param [ Array<Server> ] servers The known servers.

@return [ Array<Server> ] The servers in the replica set.

@since 2.0.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 115
def servers(servers)
  servers.select do |server|
    (replica_set_name.nil? || server.replica_set_name == replica_set_name) &&
      server.primary? || server.secondary?
  end
end
sharded?() click to toggle source

A replica set topology is not sharded.

@example Is the topology sharded?

ReplicaSet.sharded?

@return [ false ] Always false.

@since 2.0.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 130
def sharded?; false; end
single?() click to toggle source

A replica set topology is not single.

@example Is the topology single?

ReplicaSet.single?

@return [ false ] Always false.

@since 2.0.0

# File lib/mongo/cluster/topology/replica_set_no_primary.rb, line 140
def single?; false; end

end
unknown?() click to toggle source

A replica set topology is not unknown.

@example Is the topology unknown?

ReplicaSet.unknown?
