Public Member Functions
int	getModeBits () const
	Returns the mode indicator bits as an unsigned 4-bit value (range 0 to 15).
int	numCharCountBits (int ver) const
	Returns the bit width of the character count field for a segment in this mode at the given QR Code version number.

Static Public Attributes
static const Mode	ALPHANUMERIC
	Mode for encoding alphanumeric text (0-9, A-Z, space, and select symbols).
static const Mode	BYTE
	Mode for encoding arbitrary binary data.
static const Mode	ECI
	Mode for Extended Channel Interpretation designators.
static const Mode	KANJI
	Mode for encoding Shift JIS Kanji characters.
static const Mode	NUMERIC
	Mode for encoding decimal digit strings.

Detailed Description

Describes how a segment's data bits are interpreted.

Each Mode instance is immutable and defines the mode indicator bits and character count bit widths for different QR Code version ranges.
