Class DecodeHintType


  • public final class DecodeHintType
    extends java.lang.Object
    Encapsulates a type of hint that a caller may pass to a barcode reader to help it more quickly or accurately decode it. It is up to implementations to decide what, if anything, to do with the information that is supplied.
    • Field Detail

      • OTHER

        public static final DecodeHintType OTHER
        Unspecified, application-specific hint. Maps to an unspecified Object.
      • PURE_BARCODE

        public static final DecodeHintType PURE_BARCODE
        Image is a pure monochrome image of a barcode. Doesn't matter what it maps to; use Boolean.TRUE.
      • POSSIBLE_FORMATS

        public static final DecodeHintType POSSIBLE_FORMATS
        Image is known to be of one of a few possible formats. Maps to a Vector of BarcodeFormats.
      • TRY_HARDER

        public static final DecodeHintType TRY_HARDER
        Spend more time to try to find a barcode; optimize for accuracy, not speed. Doesn't matter what it maps to; use Boolean.TRUE.
      • CHARACTER_SET

        public static final DecodeHintType CHARACTER_SET
        Specifies what character encoding to use when decoding, where applicable (type String)
      • ALLOWED_LENGTHS

        public static final DecodeHintType ALLOWED_LENGTHS
        Allowed lengths of encoded data -- reject anything else. Maps to an int[].
      • ASSUME_CODE_39_CHECK_DIGIT

        public static final DecodeHintType ASSUME_CODE_39_CHECK_DIGIT
        Assume Code 39 codes employ a check digit. Maps to Boolean.
      • NEED_RESULT_POINT_CALLBACK

        public static final DecodeHintType NEED_RESULT_POINT_CALLBACK
        The caller needs to be notified via callback when a possible ResultPoint is found. Maps to a ResultPointCallback.
