Properties
- barcodeFormat → BarcodeFormat

Get the format of this decoder.

Methods
-
checkChecksum(
String s) → bool -
@param s string of digits to check
@return {@link #checkStandardUPCEANChecksum(CharSequence)}
@throws FormatException if the string does not contain only digits
inherited
-
decode(
BinaryBitmap image, [DecodeHint? hints]) → Result -
Locates and decodes a barcode in some format within an
image. This method also acceptshints, each possibly associated to some data, which may help the implementation decode.inherited -
decodeEnd(
BitArray row, int endStart) → List< int> -
inherited
-
decodeMiddle(
BitArray row, List< int> startRange, StringBuilder result) → int -
Subclasses override this to decode the portion of a barcode between the start
and end guard patterns.
override
-
decodeRow(
int rowNumber, BitArray row, DecodeHint? hints, [List< int> ? startGuardRange]) → Result -
Like {@link #decodeRow(int, BitArray, Map)}, but
allows caller to inform method about where the UPC/EAN start pattern is
found. This allows this to be computed once and reused across many implementations.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reset(
) → void -
Resets any internal state the implementation has after a decode, to prepare it
for reuse.
inherited
-
toString(
) → String -
A string representation of this object.
