Properties

Private bits

bits: number

Private characterCountBitsForVersions

characterCountBitsForVersions: Int32Array

Private stringValue

stringValue: string

Private value

value: ModeValues

Static ALPHANUMERIC

ALPHANUMERIC: Mode = new Mode(ModeValues.ALPHANUMERIC, 'ALPHANUMERIC', Int32Array.from([9, 11, 13]), 0x02)

Static BYTE

BYTE: Mode = new Mode(ModeValues.BYTE, 'BYTE', Int32Array.from([8, 16, 16]), 0x04)

Static ECI

ECI: Mode = new Mode(ModeValues.ECI, 'ECI', Int32Array.from([0, 0, 0]), 0x07)

Static FNC1_FIRST_POSITION

FNC1_FIRST_POSITION: Mode = new Mode(ModeValues.FNC1_FIRST_POSITION, 'FNC1_FIRST_POSITION', Int32Array.from([0, 0, 0]), 0x05)

Static FNC1_SECOND_POSITION

FNC1_SECOND_POSITION: Mode = new Mode(ModeValues.FNC1_SECOND_POSITION, 'FNC1_SECOND_POSITION', Int32Array.from([0, 0, 0]), 0x09)

Static Private FOR_BITS

FOR_BITS: Map<number, Mode> = new Map<number, Mode>()

Static Private FOR_VALUE

FOR_VALUE: Map<ModeValues, Mode> = new Map<ModeValues, Mode>()

Static HANZI

HANZI: Mode = new Mode(ModeValues.HANZI, 'HANZI', Int32Array.from([8, 10, 12]), 0x0D)

See GBT 18284-2000; "Hanzi" is a transliteration of this mode name.

STRUCTURED_APPEND: Mode = new Mode(ModeValues.STRUCTURED_APPEND, 'STRUCTURED_APPEND', Int32Array.from([0, 0, 0]), 0x03)

Static TERMINATOR

TERMINATOR: Mode = new Mode(ModeValues.TERMINATOR, 'TERMINATOR', Int32Array.from([0, 0, 0]), 0x00)
