Class StartupInjectorBuilder

java.lang.Object

org.apache.druid.guice.BaseInjectorBuilder<StartupInjectorBuilder>

org.apache.druid.guice.StartupInjectorBuilder

public class StartupInjectorBuilder
extends BaseInjectorBuilder<StartupInjectorBuilder>

Create the startup injector used to "prime" the modules for the main injector.

Servers call the forServer() method to configure server-style properties and the server metrics. Servers must also add org.apache.druid.initialization.ExtensionsModule which is not visible here, and can't be added in the forServer() method.

Tests and clients must provide properties via another mechanism.

If every test and client needs a module, it should be present here.

Configure the injector to not load server-only classes by binding those classes to providers of null values. Avoids accidental dependencies of test code on classes not intended for classes by preventing Guice from helpfully providing implicit instances.
