RemarksUsage in DataSource source applications
An ISubjectErrorEvent can be raised by a source application (that is, a DataSource application sending data to its DataSource peers). The following are typical situations in which a source application may wish to raise an ISubjectErrorEvent:
- A subject is not available from the back end feed system that feeds data to an IDataProvider
- A subject was available on the back end feed system but is no longer available.
Usage in DataSource sink applications
An ISubjectErrorEvent can be received by a sink application (that is, a DataSource application receiving data from its DataSource peers).
Situations where an ISubjectErrorEvent can be raised before any data is received include:
- A connected DataSource peer cannot supply data for the requested subject.
- No response has been received for the Subscription request.
Situations where an ISubjectErrorEvent can be raised after data is received include:
- The subject has been deleted by one of the sending DataSources
The Error property provides more information about why the the ISubjectErrorEvent was raised.
