Package org.apache.druid.curator.discovery

Class DiscoveryModule

java.lang.Object
org.apache.druid.curator.discovery.DiscoveryModule
All Implemented Interfaces:
com.google.inject.Module
public class DiscoveryModule extends Object implements com.google.inject.Module
The DiscoveryModule allows for the registration of Keys of DruidNode objects, which it intends to be automatically announced at the end of the lifecycle start. In order for this to work a ServiceAnnouncer instance *must* be injected and instantiated first. This can often be achieved by registering ServiceAnnouncer.class with the LifecycleModule.

      public DiscoveryModule()

  • Method Details

    • configure

      @Inject public void configure(Properties properties)

    • registerDefault

      public static void registerDefault(com.google.inject.Binder binder)
      Requests that the un-annotated DruidNode instance be injected and published as part of the lifecycle. That is, this module will announce the DruidNode instance returned by injector.getInstance(Key.get(DruidNode.class)) automatically. Announcement will happen in the ANNOUNCEMENTS stage of the Lifecycle
      Parameters:
      binder - the Binder to register with

    • register

      public static void register(com.google.inject.Binder binder, Annotation annotation)
      Requests that the annotated DruidNode instance be injected and published as part of the lifecycle. That is, this module will announce the DruidNode instance returned by injector.getInstance(Key.get(DruidNode.class, annotation)) automatically. Announcement will happen in the ANNOUNCEMENTS stage of the Lifecycle
      Parameters:
      annotation - The annotation instance to use in finding the DruidNode instance, usually a Named annotation

    • register

      public static void register(com.google.inject.Binder binder, Class<? extends Annotation> annotation)
      Requests that the annotated DruidNode instance be injected and published as part of the lifecycle. That is, this module will announce the DruidNode instance returned by injector.getInstance(Key.get(DruidNode.class, annotation)) automatically. Announcement will happen in the ANNOUNCEMENTS stage of the Lifecycle
      Parameters:
      binder - the Binder to register with
      annotation - The annotation class to use in finding the DruidNode instance

    • registerKey

      public static void registerKey(com.google.inject.Binder binder, com.google.inject.Key<DruidNode> key)
      Requests that the keyed DruidNode instance be injected and published as part of the lifecycle. That is, this module will announce the DruidNode instance returned by injector.getInstance(Key.get(DruidNode.class, annotation)) automatically. Announcement will happen in the ANNOUNCEMENTS stage of the Lifecycle
      Parameters:
      binder - the Binder to register with
      key - The key to use in finding the DruidNode instance

    • configure

      public void configure(com.google.inject.Binder binder)
      Specified by:
      configure in interface com.google.inject.Module

    • getServiceAnnouncer

      Throws:
