Detailed Description

PHP bit stream.

Class implementing array of bits (= 1 or 0 ints). Allows to initialize and append bits from given Integer or array of Bytes.

Member Function Documentation

QRbitstream::allocate

(

$setLength)

Allocates bit stream, fills bit data stream with 0's.

This operation is destructive, will replace orginal stream contents!

Parameters

Integer

$setLength

desired target stream size

Returns

Integer 0 on success, other on failure

QRbitstream::append

(

QRbitstream

$arg)

Appends given bit stream at end of this stream.

Parameters

QRbitstream

$arg

bit stream to be appended

Returns

Integer status of append operation, 0 when success, -1 when $arg is null

QRbitstream::appendBytes	(		$size,
			$data
	)

Appends bit stream created from from given byte array at end of current stream.

Parameters

Integer	$size	size of array
Array	$data	array ob bytes

Returns

Integer status of append operation, status of append operation, 0 when success, -1 otherwise

QRbitstream::appendNum	(		$bits,
			$num
	)

Appends bit stream cteated from given Integer number at end of current stream.

Parameters

Integer	$bits	bit count
Integer	$num	integer to convert

Returns

Integer status of append operation, status of append operation, 0 when success, -1 otherwise

static QRbitstream::newFromBytes (   $size,   $data  )

static

Creates new bit stream from given byte array.

Parameters

Integer	$size	size of array
Array	$data	array ob bytes

Returns

QRbitstream bit stream object containing bit contents of given bytes array

static QRbitstream::newFromNum (   $bits,   $num  )

static

Creates new bit stream from given Integer number.

Parameters

Integer	$bits	bit count
Integer	$num	integer to convert

Returns

QRbitstream bit stream object containing first $bits bits from $num in order from LSB to MSB

QRbitstream::size

(

)

Returns

Integer size of byte stream

QRbitstream::toByte

(

)

Converts current bit stream into byte array.

Returns

Array array of bytes
