Detailed Description

Represents up-to-date information about some condition or state of an external entity that updates in real-time. For example, a IDxQuote is an up-to-date information about best bid and best offer for a specific symbol.

Lasting events are conflated for each symbol. Last event for each symbol is always delivered to event listeners on subscription, but intermediate (next-to-last) events are not queued anywhere, they are simply discarded as stale events. More recent events represent an up-to-date information about some external entity.

Lasting events can be used with DXFeed.GetLastEventPromise and DXFeed.GetLastEventPromises methods to retrieve last events for each symbol. TODO: not implemented

Note, that subscription to all lasting events of a specific type via WildcardSymbol::ALL symbol object does not benefit from the above advantages of lasting events. TODO: not implemented

Template Parameters
TType of the event symbol for this event type.
