BitStream #

BitStream allows for easy manipulation of long strings of bits, for both reading and writing.

It's easy to get started:

var bitstream = BitStream();

You can also start it with a Uint8List:

var bitstream = BitStream(stream: myBytes);

To write to the stream:

bitstream.write(5,bits: 3); //writes 101 (binary) to the stream
bitstream.writeBool(true); //writes 1 (binary) to the stream
bitstream.writeBytes(Uint8List.fromList(<int>[0,255,127]),bytes:3); //writes 0x00FF7F to the stream
bitstream.output(); //will output 1011000000001111111101111111 to the console

Reading is also easy:

bitstream.read(bits:5); //reads 22 (decimal) from the stream
bitstream.read(bits:11); //reads 15 (decimal) from the stream
bitstream.readBool(); //reads true from the stream

Supported Data Types #

Data Type Read Method Write Method
int read({bytes, bits}) write(input, {bytes, bits})
bool readBool() writeBool(input)
string (ASCII) readAsciiString({bytes, bits}) writeAsciiString(input, {bytes, bits})
string (HEX) readHexString({bytes, bits}) writeHexString(input, {bytes, bits})
Uint8List readBytes({bytes, bits}) writeBytes(input, {bytes, bits})
BitStream readBitStream({bytes, bits}) writeBitStream(input, {bytes, bits})

Additional Methods #

Method Name Description
checkBit(int bit) Returns a bool if a bit is set or not (does not progress the cursor)
output() Prints a binary representation of the current stream to the console
toString() Returns a binary representation of the current stream
getStream() Gets the current stream data as a Uint8List
getLength() Gets the current length of the stream
getCursor() Gets the current cursor position
resetCursor() Resets the cursor position
