shared_ptr< UdpChannel > nfd::UdpFactory::createChannel	(	const udp::Endpoint &	localEndpoint,
		const time::seconds &	timeout = `time::seconds(600)`
	)

Create UDP-based channel using udp::Endpoint.

udp::Endpoint is really an alias for boost::asio::ip::udp::endpoint.

If this method called twice with the same endpoint, only one channel will be created. The second call will just retrieve the existing channel.

If a multicast face is already active on the same local endpoint, the creation fails and an exception is thrown

Once a face is created, if it doesn't send/receive anything for a period of time equal to timeout, it will be destroyed

Todo:: this funcionality has to be implemented

Returns: always a valid pointer to a UdpChannel object, an exception is thrown if it cannot be created.

Exceptions

UdpFactory::Error

		const time::seconds &	timeout = `time::seconds(600)`
	)

Create UDP-based channel using specified IP address and port number.

This method is just a helper that converts a string representation of localIp and port to udp::Endpoint and calls the other createChannel overload.

If localHost is a IPv6 address of a specific device, it must be in the form: ip addressinterface name Example: fe80::5e96:9dff:fe7d:9c8den1 Otherwise, you can use ::

Exceptions

UdpChannel::Error	if the bind on the socket fails

		const udp::Endpoint &	multicastEndpoint,
		const std::string &	networkInterfaceName = `""`
	)

Create MulticastUdpFace using udp::Endpoint.

udp::Endpoint is really an alias for boost::asio::ip::udp::endpoint.

The face will join the multicast group

If this method called twice with the same endpoint and group, only one face will be created. The second call will just retrieve the existing channel.

If an unicast face is already active on the same local NIC and port, the creation fails and an exception is thrown

Parameters

networkInterfaceName name of the network interface on which the face will be bound (Used only on multihomed linux machine with more than one MulticastUdpFace for the same multicast group. If specified, will requires CAP_NET_RAW capability) An empty string can be provided in other system or in linux machine with only one MulticastUdpFace per multicast group

Returns: always a valid pointer to a MulticastUdpFace object, an exception is thrown if it cannot be created.

Exceptions

UdpFactory::Error
