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
