Function createBitReader

createBitReader(
source: ArrayBuffer | TypedArray,
options?: BitReaderOptions,
): BitReader

Create a new BitReader from source bytes.

Parameters

source: ArrayBuffer | TypedArray
The source data for the reader.
options: BitReaderOptions = {}

Returns BitReader

Example: Reading in most-significant bits first mode.

const source = Uint8Array.of(0b1110_0001);
const br = createBitReader(source, { mode: 'msb' });

br.read32(3); // 0b111
br.read32(1); // 0b0
br.read32(3); // 0b000
br.read32(1); // 0b1

Example: Reading in least-significant bits first mode.

const source = Uint8Array.of(0b1110_0001);
const r = createBitReader(source, { mode: 'lsb' });

br.read32(3); // 0b001
br.read32(1); // 0b0
br.read32(3); // 0b110
br.read32(1); // 0b1
