Syntax
static FOnConnection OnConnection;
Remarks
Delegate that triggers when a connection is established. Gives subscribers a chance to trace events that appear after important events but before regular events (including tail). The following restrictions apply:
- Only NoSync event types can be emitted.
- Important events should not be emitted. They will appear after the events in the tail.
- Callback is issued from a worker thread. User is responsible to synchronize shared resources.
This is an advanced feature to avoid using important events in cases where event data can be recalled easily.
