C++ (Cpp) UPDATE_AMOUNT_OF_GEOMETRY_MEMORY Examples

Example #1

File: gdal_multipoint.cpp Project: jarped/node-gdal

Handle<Value> MultiPoint::New(OGRMultiPoint *geom, bool owned)
{
	HandleScope scope;

	if (!geom) {
		return Null();
	}

	//make a copy of geometry owned by a feature
	// + no need to track when a feature is destroyed
	// + no need to throw errors when a method trys to modify an owned read-only geometry
	// - is slower

	if (!owned) {
		geom = static_cast<OGRMultiPoint*>(geom->clone());
	}

	MultiPoint *wrapped = new MultiPoint(geom);
	wrapped->owned_ = true;

	UPDATE_AMOUNT_OF_GEOMETRY_MEMORY(wrapped);

	v8::Handle<v8::Value> ext = v8::External::New(wrapped);
	v8::Handle<v8::Object> obj = MultiPoint::constructor->GetFunction()->NewInstance(1, &ext);

	return scope.Close(obj);
}

Example #2

Local<Value> LineString::New(OGRLineString *geom, bool owned)
{
	Nan::EscapableHandleScope scope;

	if (!geom) {
		return scope.Escape(Nan::Null());
	}

	//make a copy of geometry owned by a feature
	// + no need to track when a feature is destroyed
	// + no need to throw errors when a method trys to modify an owned read-only geometry
	// - is slower

	if (!owned) {
		geom = static_cast<OGRLineString*>(geom->clone());
	};

	LineString *wrapped = new LineString(geom);
	wrapped->owned_ = true;

	UPDATE_AMOUNT_OF_GEOMETRY_MEMORY(wrapped);

	Local<Value> ext = Nan::New<External>(wrapped);
	Local<Object> obj = Nan::New(LineString::constructor)->GetFunction()->NewInstance(1, &ext);

	return scope.Escape(obj);
