C++ (Cpp) Dart_ThrowException Examples

Example #1

File: Exception.cpp Project: richardeakin/Cinder-Dart

// FIXME: apparently this can't be called unless we're inside a Dart_Invoke, maybe need to move it to Script and keep track of that
// - but this isn't feasible for things like cidart::getValue(), since it doesn't know of the current script
// - possible hack solution: get the stacktrace and search for the invoke() command, if we don't find that then throw regularly
// - PROBABLE SOLUTION: build dart runtime with exceptions enabled and throw regular C++ exception
void throwException( const std::string &description )
{
	cidart::DartScope enterScope;

	Dart_Handle exceptionHandle = toDart( description );
	CIDART_CHECK( Dart_ThrowException( exceptionHandle ) );
}

Example #2

File: Canvas.cpp Project: zbowling/engine

static void Canvas_setMatrix(Dart_NativeArguments args) {
  DartArgIterator it(args);
  Float64List matrix4 = it.GetNext<Float64List>();
  if (it.had_exception())
    return;
  ExceptionState es;
  GetReceiver<Canvas>(args)->setMatrix(matrix4, es);
  if (es.had_exception())
    Dart_ThrowException(es.GetDartException(args, true));
}

Example #3

File: SceneBuilder.cpp Project: algor/engine

static void SceneBuilder_pushTransform(Dart_NativeArguments args) {
  DartArgIterator it(args);
  Float64List matrix4 = it.GetNext<Float64List>();
  if (it.had_exception())
    return;
  ExceptionState es;
  GetReceiver<SceneBuilder>(args)->pushTransform(matrix4, es);
  if (es.had_exception())
    Dart_ThrowException(es.GetDartException(args, true));
}

Example #4

File: ImageShader.cpp Project: Rajesh-Veeranki/engine

static void ImageShader_initWithImage(Dart_NativeArguments args) {
  DartArgIterator it(args);
  CanvasImage* image = it.GetNext<CanvasImage*>();
  SkShader::TileMode tmx = it.GetNext<SkShader::TileMode>();
  SkShader::TileMode tmy = it.GetNext<SkShader::TileMode>();
  Float64List matrix4 = it.GetNext<Float64List>();
  if (it.had_exception())
    return;
  ExceptionState es;
  GetReceiver<ImageShader>(args)->initWithImage(image, tmx, tmy, matrix4, es);
  if (es.had_exception())
    Dart_ThrowException(es.GetDartException(args, true));
}

Example #5

File: test_extension.c Project: MikeSanti/bleeding_edge

void ThrowMeTheBall(Dart_NativeArguments arguments) {
  Dart_Handle object = Dart_GetNativeArgument(arguments, 0);
  Dart_ThrowException(object);
}
