Property TEurekaExceptionInfo.ExceptionObject

Previous pageReturn to chapter overviewNext page   

Exception object.

 

Unit

EException

 

Value

Exception object type-casted as pointer. I.e. it's a pointer to data of exception object.

 

Remarks

This is pointer to original exception object.

Warning

Since exception may come from another (external) executable module (rare cases, but could happen), then exception object may be not a Delphi object. Do not try to cast this value to Exception or TObject unless you're 100% sure about this.

 

Use Address, ExceptionClass and ExceptionMessage properties instead.

 

 

Examples

 

Code (Delphi)

// This will add custom info to bug report

procedure AddMyData(const ACustom: Pointer;

 AExceptionInfo: TEurekaExceptionInfo;

 ALogBuilder: TBaseLogBuilder;

 ADataFields: TStrings;

 var ACallNextHandler: Boolean);

 

// Extract native Delphi exception from exception info

function GetExceptionObject(AExceptionInfo: TEurekaExceptionInfo): Exception;

var

EObj: TObject;

begin

// Exception was thrown by a compatible Delphi version?

if AExceptionInfo.ExceptionNative then

EObj := TObject(AExceptionInfo.ExceptionObject)

else

EObj := nil; // rare

 

// Exception is SysUtils.Exception?

if EObj is Exception then

Result := Exception(EObj)

else

Result := nil; // very rare

end;

 

var

E: Exception;

begin

E := GetExceptionObject(AExceptionInfo);

 // E is either nil (for non-Delphi exceptions)

 // or E is current Exception

 

// Add custom info for custom exceptions

if E is EMyException then

ADataFields.Values['Code'] := EMyException(E).Code;

end;

 

initialization

RegisterEventCustomDataRequest(nil, AddMyData);

end.
