HostNameSubscriptionListener

Defined in fuchsia.net.mdns/host_name_subscriber.fidl

Client-implemented interface for subscribers. Method replies are used to throttle traffic. The service won't necessarily wait for a reply before calling another method.

Added: 9

Request

Name	Type
`addresses`	`vector<HostAddress>[64]`

Response

ProxyHostPublisher

Defined in fuchsia.net.mdns/proxy_host_publisher.fidl

Discoverable protocol for publishing on behalf of another host.

Added: 9

PublishProxyHost

Publishes a host name on behalf of a remote host and provides a ServiceInstancePublisher for publishing service instances on behalf of that host.

request host host name to publish.
request addresses addresses to publish for the host name.
request options options to be applied to the publication.
request service_instance_publisher server end of the ServiceInstancePublisher for the proxied host.

This method causes the service to publish the host name at the specified addresses. The actual host must not be present on any relevant links or there will be a conflict. If the perform_probe option is true or not supplied (true by default), a probe will occur to verify that the host name isn't otherwise published.

The proxy host created by this method persists until the ServiceInstancePublisher channel is closed.

Request

Name	Type
`host`	`host_name`

PublicationResponder

Defined in fuchsia.net.mdns/mdns.fidl

Client-supplied publication responder interface.

Deprecated: 9

OnPublication

Provides instance information for initial announcements and query responses relating to the service instance specified in ServiceInstancePublisher.PublishServiceInstance. If the publication relates to a subtype of the service, subtype contains the subtype, otherwise it is null. If publication is null, no announcement or response is transmitted. Strings in text are transmitted in the TXT record.

Reannounce

Initiates reannouncement of the service instance due to a change in the instance's port number or text strings. All announcements are filtered through OnPublication, which replies with the new port and text values.

Response

<EMPTY>

SetSubtypes

Sets the subtypes for the service instance. The specified subtypes will be announced subject to filtering through the responder. The initial subtype collection is empty.

Response

Publisher

Defined in fuchsia.net.mdns/mdns.fidl

This value should be true unless the instance name is known to be unique.

If a service with the same service and instance names is already published, the old publication will be terminated, and the responder channel for the old publication will be closed.
