Engine Events

The Engine class exposes the following events:

Event	Description
Error	Error condition is detected
IncomingTelecommunicationLink	Incoming telecommunication link is detected
IncomingConnection	Incoming FIX Connection is detected.
UnknownIncomingConnection	Unknown incoming FIX Connection is detected, see Accepting FIX Session Without a Prior Creation of Session Object
Warning	Warning condition is detected

Note

Engine event handling is a synchronous operation. Avoid performing time-consuming tasks inside event handlers.

For example:

engine.Error += (object sender, EngineErrorEventArgs e) =>
{
    Console.WriteLine($"Error condition is detected: {e}");
};

engine.IncomingTelecommunicationLink += (object sender, IncomingTelecommunicationLinkEventArgs e) =>
{
    Console.WriteLine($"Incoming telecommunication link: {e}");
};

engine.IncomingConnection += (object sender, IncomingConnectionEventArgs e) =>
{
    Console.WriteLine($"Incoming connection: {e}");
};

engine.UnknownIncomingConnection += (object sender, UnknownIncomingConnectionEventArgs e) =>
{
    Console.WriteLine($"Unknown incoming connection: {e}");
};

engine.Warning += (object sender, EngineWarningEventArgs e) =>
{
    Console.WriteLine($"Warning condition is detected: {e}");
};

Rejecting Incoming Telecommunication Link

To reject the incoming telecommunication link, set AcceptConnection to false.

For example:

engine.IncomingTelecommunicationLink += (object sender, IncomingTelecommunicationLinkEventArgs e) =>
{
    Console.WriteLine($"Incoming telecommunication link will be rejected: {e}");

    e.AcceptConnection = false;
};

Rejecting Incoming Connection

To reject the incoming connection, put any reason text to RejectReason or leave it blank to accept. Please, pay attention that the text will be send to Initiator in a logout message if SendLogoutOnInvalidLogon is true.

For example:

engine.IncomingConnection += (object sender, IncomingConnectionEventArgs e) =>
{
    Console.WriteLine($"Incoming connection will be rejected: {e}");

    e.RejectReason = "Wrong logon details";
};
