Class ServiceRegistryHolder

java.lang.Object

eu.cloudnetservice.driver.registry.ServiceRegistryHolder

@Internal
final class ServiceRegistryHolder
extends Object

Holds the singleton instance of the service registry which is returned by ServiceRegistry.registry(). The instance is retrieved from the boot injection layer upon the first invocation of the mentioned method and will not change over the lifetime of the jvm. Injecting the service registry should yield the same result as using the static accessor method. The static method is more of a helper function for internal code which has no direct access to dependency injection, for example to construct builder instances, but still want to facility the instance retrieval for the user.
