Class DruidInjectorBuilder

java.lang.Object
org.apache.druid.guice.DruidInjectorBuilder
Direct Known Subclasses:
CoreInjectorBuilder, ExtensionInjectorBuilder, ServiceInjectorBuilder
public class DruidInjectorBuilder extends Object
Druid-enabled injector builder which supports DruidModules, module classes created from the base injector, and filtering based on properties and LoadScope annotations.

Can be used in clients and tests, in which case no module filtering is done. Presumably, the test or client has already selected the modules that it needs.

Druid injector builders can be chained with an earlier builder providing a set of modules which a later builder overrides. Again, this is typically used only in the server, not in clients or tests.

  • Method Details

    • ignoreLoadScopes

      public DruidInjectorBuilder ignoreLoadScopes()
      Ignore load scope annotations on modules. Primarily for testing where a unit test is not any Druid node, and may wish to load a module that is annotated with a load scope.

    • add

      public DruidInjectorBuilder add(Object... input)
      Add an arbitrary set of modules.

    • addModules

      public DruidInjectorBuilder addModules(com.google.inject.Module... inputs)

    • addAll

      public DruidInjectorBuilder addAll(Iterable<? extends Object> inputs)

    • addInput

      public DruidInjectorBuilder addInput(Object input)
      Add an arbitrary Module, DruidModule instance, or a subclass of these classes. If a class is provided, it is instantiated using the base injector to allow dependency injection. If a module instance is provided, its members are injected. Note that such modules have visibility only to objects defined in the base injector, but not to objects defined in the injector being built.

      public DruidInjectorBuilder addModule(com.google.inject.Module module)
