Detailed Description

Represents an event raised when there is an error in a subscription to a subject.

Usage 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 Caplin.DataSource.Publisher.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.
