public final class BarcodeFormat

Object
BarcodeFormat

The normalized symbology names Barcode.getFormat() reports, as constants instead of literals. Every backend maps its own vendor identifier onto one of these before the result reaches application code, and reports UNKNOWN for a symbology outside this set.

scanner.process(VisionImage.encoded(jpeg)).ready(codes -> {
    for (Barcode code : codes) {
        if (BarcodeFormat.matches(code, BarcodeFormat.QR_CODE)) {
            Log.p("QR: " + code.getValue());
        } else if (BarcodeFormat.matches(code, BarcodeFormat.EAN_13,
                BarcodeFormat.UPC_A)) {
            lookUpProduct(code.getValue());
        }
    }
});

Method details

matches

public static boolean matches(Barcode barcode, String... formats)

Tests a decoded barcode against a set of accepted formats. An empty or null format list accepts every symbology, which is what a general-purpose scanner wants.

Parameters

barcode Barcode: observation to test, or null
formats String...: accepted format constants

Returns

true when the barcode’s format is one of formats
