## OneDExtendedParameters class

Stores special data of 1D recognized barcode like separate codetext and checksum

```js
new OneDExtendedParameters()
```

**Example:**

```js
//This sample shows how to get 1D barcode value and checksum
let generator = new BarcodeGenerator(EncodeTypes.EAN_13, "1234567890128");
generator.save("test.png");
let reader = new BarCodeReader("test.png", null,  DecodeType.EAN_13);
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
   let result = results[i];
   console.log("BarCode Type: " + result.getCodeTypeName());
   console.log("BarCode CodeText: " + result.getCodeText());
   console.log("BarCode Value: " + result.getExtended().getOneD().getValue());
   console.log("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
}
```
