Members

Functions

equals bool equals(FormatInformation other): Verifies if this instance equals another one.
getDataMask int getDataMask(): Gets the data mask.
getErrorCorrectionLevel ErrorCorrectionLevel getErrorCorrectionLevel(): Gets the error correction level.
hashCode int hashCode(): Hashes the code of the EC level.

Static functions

decodeFormatInformation FormatInformation decodeFormatInformation(int maskedFormatInfo1, int maskedFormatInfo2): Decodes format information.
doDecodeFormatInformation FormatInformation doDecodeFormatInformation(int maskedFormatInfo1, int maskedFormatInfo2): Internal method for decoding format information.
numBitsDiffering int numBitsDiffering(int a, int b): Checks how many bits are different between two integers.

Static variables

bitsSetInHalfByte int[] bitsSetInHalfByte;: Offset i holds the number of 1 bits in the binary representation of i.
formatInfoDecodeLookup int[][] formatInfoDecodeLookup;: Lookup table for decoding format information.

Variables

FORMAT_INFO_MASK_QR enum int FORMAT_INFO_MASK_QR;: Mask for format information.
dataMask int dataMask;: Data mask.
ecLevel ErrorCorrectionLevel ecLevel;: Error correction level.
