Method Detail

lookup

public abstract scala.concurrent.Future<ServiceDiscovery.Resolved> lookup(Lookup lookup,
                                                                          scala.concurrent.duration.FiniteDuration resolveTimeout)

lookup

public scala.concurrent.Future<ServiceDiscovery.Resolved> lookup(java.lang.String serviceName,
                                                                 scala.concurrent.duration.FiniteDuration resolveTimeout)

Scala API: Perform lookup using underlying discovery implementation.

Convenience for when only a name is required.

Parameters:

serviceName - (undocumented)

resolveTimeout - (undocumented)

Returns:

(undocumented)

lookup

public java.util.concurrent.CompletionStage<ServiceDiscovery.Resolved> lookup(Lookup query,
                                                                              java.time.Duration resolveTimeout)

Java API: Perform basic lookup using underlying discovery implementation.

While the implementation may provide other settings and ways to configure timeouts, the passed resolveTimeout should never be exceeded, as it signals the application's eagerness to wait for a result for this specific lookup.

The returned future SHOULD be failed once resolveTimeout has passed.

Parameters:

query - (undocumented)

resolveTimeout - (undocumented)

Returns:

(undocumented)

lookup

public java.util.concurrent.CompletionStage<ServiceDiscovery.Resolved> lookup(java.lang.String serviceName,
                                                                              java.time.Duration resolveTimeout)

Java API

Parameters:

serviceName - A name, see discovery-method's docs for how this is interpreted

resolveTimeout - Timeout. Up to the discovery-methodto adhere to his

Returns:

(undocumented)
