# Interface EnvironmentalShadowBuilder

All Known Implementing Classes:
  `EnvironmentalShadowBuilderImpl`

public interface EnvironmentalShadowBuilder
Much like `PropertyShadowBuilder`, except that instead of accessing a property of some other service, it accesses a value from within the `Environment` service. This is useful for defining a new service that can be injected into other services (whereas the `Environmental` annotation may only be used within component classes).

  - ### build

    <T> T build(Class<T> serviceType)
    Returns a proxy that delegates all methods to an object obtained from `Environment.peekRequired(Class)`. Note that at the time this method is invoked, the Environment service may still be virtual, and will often not yet have been loaded with values, and that's OK, the resolution is deferred to the instant a method is invoked.
    Type Parameters:
      `T` -
    Parameters:
      `serviceType` - the service type, which is used to obtained the delegate instance
    Returns:
      a proxy to the service
