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).
