connectNewNode()

std::string RAFTConsensus::connectNewNode ( boost::shared_ptr< TcpConnection >  connection, std::string  request  )

virtual

Will handle a connect request by a new node that wants to join the network. If this node is the leader, we will add it to our list of connections. If we are not the leader, we will return the ip and port of the leader of the network.

Returns

If we are the leader, we will return ok and the initial data. If we are not the leader, we will return the leader of the network.

getCurrentIPs()

std::vector< std::string > RAFTConsensus::getCurrentIPs ( )

virtual

Returns the ips currently know to this api.

Returns

List of ips with port.

getIps()

std::vector< std::pair< std::string, std::string > > RAFTConsensus::getIps ( std::string  file = ".env" )

virtual

Reads the given file and gets the ips out of it.

Returns

List of ips with port.

getMyIP()

virtual std::string RAFTConsensus::getMyIP ( )

inlinevirtual

Gets the ip of this node.

Returns

The own ip address.

passRequestToLeader()

std::string RAFTConsensus::passRequestToLeader ( std::string  requestType, std::string  client, std::string  request  )

virtual

Will pass the given request on to the leader of the network.

Returns

The string that the leader gives back.

start()

void RAFTConsensus::start	(	RequestHandler *	requestHandler,
		std::vector< std::pair< std::string, std::string > >	ips,
		bool	assumeLeader = false
	)

Starts RAFT. Will try to connect to a set list of IP's where we assume the leaders are. If none of them respond, we will assume we are the first and assume the role of leader.

Parameters

assumeLeader

If set to true, will skip the connect phase and assume that this node is the leader.
