Class | Description |
---|---|
BitArray |
A simple, fast array of bits, represented compactly by an array of ints internally.
|
BitMatrix |
Represents a 2D matrix of bits.
|
BitVector |
JAVAPORT: This should be combined with BitArray in the future, although that class is not yet dynamically resizeable.
|
ByteArray |
This class implements an array of unsigned bytes.
|
ByteMatrix |
A class which wraps a 2D array of bytes.
|
CharacterSetECI |
Encapsulates a Character Set ECI, according to "Extended Channel Interpretations" 5.3.1.1 of ISO 18004.
|
EncodeHintType |
These are a set of hints that you may pass to Writers to specify their behavior.
|
Encoder | |
ErrorCorrectionLevel |
See ISO 18004:2006, 6.5.1.
|
GF256 |
This class contains utility methods for performing mathematical operations over the Galois Field GF(256).
|
MaskUtil | |
MatrixUtil | |
Mode |
See ISO 18004:2006, 6.4.1, Tables 2 and 3.
|
QRCode | |
QRCodeWriter |
This object renders a QR Code as a ByteMatrix 2D array of greyscale values.
|
ReedSolomonEncoder |
Implements Reed-Solomon enbcoding, as the name implies.
|
Version |
See ISO 18004:2006 Annex D
|
Version.ECB |
Encapsualtes the parameters for one error-correction block in one symbol version.
|
Version.ECBlocks |
Encapsulates a set of error-correction blocks in one symbol version.
|
Exception | Description |
---|---|
ReedSolomonException |
Thrown when an exception occurs during Reed-Solomon decoding, such as when there are too many errors to correct.
|
WriterException |
A base class which covers the range of exceptions which may occur when encoding a barcode using the Writer framework.
