DruidInjectorBuilder (druid-server 29.0.1 API)

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 Detail
- 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(List<? 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.
- addModule
```
public DruidInjectorBuilder addModule(com.google.inject.Module module)
```
- addClass
```
public DruidInjectorBuilder addClass(Class<?> input)
```
- modules
```
public List<com.google.inject.Module> modules()
```
- build
```
public com.google.inject.Injector build()
```
