Detailed Description

Represents an event that is raised when there is a change in the status of a Subject.

An Caplin.DataSource.ISubjectStatusEvent can be raised by an Caplin.DataSource.Publisher.IDataProvider to indicate to peers the status of their subscription to a subject. For example, if the back end system that feeds data to an Caplin.DataSource.Publisher.IDataProvider goes down, the IDataProvider should raise a ISubjectStatusEvent with a Caplin.DataSource.IStatusEvent.Status of Caplin.DataSource.SubjectStatus.Stale to indicate to the peer that the data it has is not completely up-to-date. When an update is subsequently received from the backend data feed, then the IDataProvider should raise a ISubjectStatusEvent with a Caplin.DataSource.IStatusEvent.Status of Caplin.DataSource.SubjectStatus.Ok to indicate to the peer that the data it has is now up to date.
