class MdnsInterfaceTransceiver

class MdnsInterfaceTransceiver

Defined at line 28 of file ../../src/connectivity/network/mdns/service/transport/mdns_interface_transceiver.h

Handles mDNS communication for a single NIC. This class is abstract and has

two concrete implementations providing family-specific behavior:

|MdnsInterfaceTransceiverV4| and |MdnsInterfaceTransceiverV6|.

Protected Members

static const int kTimeToLive_
static const size_t kMaxPacketSize

Public Methods

std::unique_ptr<MdnsInterfaceTransceiver> Create (inet::IpAddress address, const std::string & name, uint32_t id, Media media)

Creates the variant of |MdnsInterfaceTransceiver| appropriate for the

address family specified in |address|.

void SetInterfaceAddresses (const std::vector<inet::IpAddress> & interface_addresses)

Sets the list of all addresses for the interface.

void SendMessage (const DnsMessage & message, const inet::SocketAddress & address)

Sends a message to the specified address. A V6 interface will send to

|MdnsAddresses::V6Multicast| if |address| is |MdnsAddresses::V4Multicast|. If any resource

section of the message contains one or more address placeholders, those placeholders will be

replaced by address resource records for all this interface's addresses.

void SendAddress (const DnsName & host_full_name)

Sends a message containing only an address resource for this interface.

Defined at line 133 of file ../../src/connectivity/network/mdns/service/transport/mdns_interface_transceiver.cc

void SendAddressGoodbye (const DnsName & host_full_name)

Sends a message containing only an address resource for this interface with

zero ttl, indicating that the address is no longer valid.

void LogTraffic ()

Writes log messages describing lifetime traffic.

const std::vector<std::shared_ptr<DnsResource>> & GetInterfaceAddressResources (const DnsName & host_full_name)

Returns address resource (A/AAAA) records with the given name and the

addresses contained in |interface_addresses_|.

This method is protected so it can be accessed by subclasses used in tests.
