## QRExtendedParameters class

Stores a QR Structured Append information of recognized barcode

```js
new QRExtendedParameters()
```

**Example:**

```js
//This sample shows how to get QR Structured Append data

let reader = new BarCodeReader("test.png", null,  DecodeType.QR);
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("QR Structured Append Quantity: " + result.getExtended().getQR().getQRStructuredAppendModeBarCodesQuantity());
   console.log("QR Structured Append Index: " + result.getExtended().getQR().getQRStructuredAppendModeBarCodeIndex());
   console.log("QR Structured Append ParityData: " + result.getExtended().getQR().getQRStructuredAppendModeParityData());
}
```
