Returns the number of decoded barcodes in the unit.

### getDecodedBarcode

Gets the `DecodedBarcodeElement` object at the specified index.

```java
public DecodedBarcodeElement getDecodedBarcode(int index) throws BarcodeReaderException
```

**Parameter**

`index` The index of the desired `DecodedBarcodeElement` object.

**Return value**
