Method Detail

cached

public scala.Option<Dns.Resolved> cached(java.lang.String name,
                                         ActorSystem system)

Deprecated.

use cached(DnsProtocol.Resolve). Since 2.6.0.

Lookup if a DNS resolved is cached. The exact behavior of caching will depend on the akka.actor.io.dns.resolver that is configured.

resolve

public scala.Option<Dns.Resolved> resolve(java.lang.String name,
                                          ActorSystem system,
                                          ActorRef sender)

Deprecated.

use resolve(DnsProtocol.Resolve). Since 2.6.0.

If an entry is cached return it immediately. If it is not then trigger a resolve and return None.

cached

public scala.Option<DnsProtocol.Resolved> cached(DnsProtocol.Resolve name,
                                                 ActorSystem system)

Lookup if a DNS resolved is cached. The exact behavior of caching will depend on the akka.actor.io.dns.resolver that is configured.

resolve

public scala.Option<DnsProtocol.Resolved> resolve(DnsProtocol.Resolve name,
                                                  ActorSystem system,
                                                  ActorRef sender)

If an entry is cached return it immediately. If it is not then trigger a resolve and return None.

lookup

public Dns$ lookup()

Description copied from interface: ExtensionIdProvider

Returns the canonical ExtensionId for this Extension

Specified by:

lookup in interface ExtensionIdProvider

createExtension

public DnsExt createExtension(ExtendedActorSystem system)

Description copied from interface: ExtensionId

Is used by Akka to instantiate the Extension identified by this ExtensionId, internal use only.

Specified by:

createExtension in interface ExtensionId<DnsExt>

get

public DnsExt get(ActorSystem system)

Java API: retrieve the Udp extension for the given system.

Specified by:

get in interface ExtensionId<DnsExt>

get

public DnsExt get(ClassicActorSystemProvider system)

Description copied from interface: ExtensionId

Returns an instance of the extension identified by this ExtensionId instance. Java API For extensions written in Scala that are to be used from Java also, this method should be overridden to get correct return type.

 override def get(system: ClassicActorSystemProvider): TheExtension = super.get(system)
 

Specified by:

get in interface ExtensionId<DnsExt>
