public interface PushConnection extends Serializable
PushConnection
instance is bound to a UI as
long as push is enabled in that UI, even if the actual connection is
momentarily dropped either due to a network failure or as a normal part of
the transport mechanism.
This interface is an internal API, only meant to be used by the framework. May be renamed or removed in a future release.
