Class GenericMultipleBarcodeReader

java.lang.Object
  com.google.zxing.multi.GenericMultipleBarcodeReader

All Implemented Interfaces:

MultipleBarcodeReader

public final class GenericMultipleBarcodeReader
extends Object
implements MultipleBarcodeReader

Attempts to locate multiple barcodes in an image by repeatedly decoding portion of the image. After one barcode is found, the areas left, above, right and below the barcode's ResultPoints are scanned, recursively.

A caller may want to also employ ByQuadrantReader when attempting to find multiple 2D barcodes, like QR Codes, in an image, where the presence of multiple barcodes might prevent detecting any one of them.

That is, instead of passing a Reader a caller might pass new ByQuadrantReader(reader).
