OnException Event

Fires whenever an unhandled exception is raised while processing a client connection.

Syntax

property OnException: TsgcExceptionEvent;
// TsgcExceptionEvent = procedure(Connection: TsgcWSConnection; E: Exception) of object

Default Value

—

Remarks

OnException is raised whenever an exception escapes internal processing, for example when writing to a socket that the client has already dropped, when a user event handler throws, or when the TCP read fails unexpectedly. The E parameter exposes the exception instance so the application can log the message or react to specific classes. By default a disconnection raises an exception here; set Options.RaiseDisconnectExceptions to False to suppress those disconnect-related exceptions.

Example

procedure OnException(Connection: TsgcWSConnection; E: Exception);
begin
  WriteLn('#exception: ' + E.Message);
end;
