A class that stores the globally accessible state of a server instance.
This is a readonly class that is initialized when the server starts up. It provides access to global objects and data that different parts of the server may require. It also defines some global methods. This object is constructed is three steps: - the configuration is provided. - the node managers et. al. are provided. - the session/subscription managers are provided. The server is not running until all three steps are complete. The references returned from this object do not change after all three states are complete. This ensures the object is thread safe even though it does not use a lock. Objects returned from this object can be assumed to be threadsafe unless otherwise stated.
Inheritance: IServerInternal, IDisposable
