Class BarcodeDecoder

java.lang.Object
  net.rim.device.api.barcodelib.BarcodeDecoder

public class BarcodeDecoder
extends Object

A barcode decoder class that recognizes 1D and 2D barcodes. Supported formats are those that are supported by the included com.google.zxing library.

To ensure faster processing, you should always attempt to configure this decoder to only decode barcode types you wish to process. The following is an example on how to configure a BarcodeDecoder which is configured to scan for QR codes only.

 
 Hashtable hints = new Hashtable()
 Vector formats  = new Vector();
 formats.addElement(BarcodeFormat.QR_CODE);
 hints.put(DecodeHintType.POSSIBLE_FORMATS, formats);
 hints.put(DecoderHintType.TRY_HARDER, Boolean.TRUE);
 BarcodeDecoder decoder = new BarcodeDecoder(hints);
