NodeJS Buffer interface provides a way to manipulate bytes, but what if we needed to manipulate bits?
This library was created to address the gap of a built-in bit interface.
npm install bitview --save
new BitView(Length)
new BitView(buffer)
new BitView(buffer, byteOffset, length);
Buffer.from(arg)
length: length in bits
buffer: use an existing buffer
arg: Another interface to create a new BitView instance
arg could be an array of bits [1,0,1] or a string '1010' or a buffer.
byteOffset: default 0, starting offset of the bitview.
flips the value of the bit at location pos
Returns the value of the bit at location pos (0 or 1)
Sets the value of a bit at location pos to v
Returns a string representation of the BitView.
Returns the buffer used by the view.
Returns length in bits.
Usage:
const BitView = require("bitview")
const view= new BitView(10);
view.set(0,true);
console.log(view.get(0)); // true
view.flip(0)
console.log(view.get(0)); // false
const view2=BitView.from('101010');
console.log(view2.get(2)); // true
const view3=BitView.from([1, 0, 1]);
console.log(view3.get(1)); // false
console.log(view3.get(2)); // trueBitView uses bitwise operations to manipulate each bit in a buffer (Low Complexity)
