Method event handler for OnRaise event.

 

Unit

EEvents

 

Syntax

 

TELEvRaiseMeth = procedure(

AExceptionInfo: TEurekaExceptionInfo;

var ACallNextHandler: Boolean

) of object;

 

Parameters

AExceptionInfo [in]

Information about exception.

 

ACallNextHandler [out]

True (default) - call next registered event handler, False - do not call next event handler.

 

Remarks

OnRaise event is fired for each raised exception. You can use this event to collect additional information about exception, to change existing information or place any other custom logic.

Important!

Do not place exception processing code into event handler for this event. Use OnExceptionNotify event instead.

 

Caution!

Any event is called from the context of exception thread, which may be not the main thread of application. Thus, it's highly recommended to avoid using any global-like data and to avoid access VCL objects. If you still need to do any of that - please use proper thread synchronization for globals and Synchronize method for VCL access.

 

 

Examples

 

Code (Delphi)

raise Exception.Create('Error'); // - event will be raised here

 

See this article for example of registering event handlers.

 

Sample event handler may look like this:

 

Code (Delphi)

procedure TMyObject.OnRaise(AExceptionInfo: TEurekaExceptionInfo; var ACallNextHandler: Boolean);

begin

 // Collect additional information for exception

 AExceptionInfo.AdditionalInfo := 'Sample additional data';

end;
