node-byte-vector

ByteVector for node.js. Perfect for binary data.

Usage:

var ByteVector = requite('bytevector'),
    vector = new ByteVector([1, 2, 3, 4, 5]); // Our vector

vector.push_back(6); // Insert binary value '6' in the end
vector.pop_front(); // Remove first value (1).

var copy = new ByteVector(vector); // [2, 3, 4, 5, 6]

##Features:

  • Space effcient. Each element will only use 8 bits memory.
  • Performance wise. It is so fast it can principle be.

##Good to know All values are saved in a Uint8Array instance which only accepts integer values between 0-255. I

##Methods

###Constructor(int): Construct an empty vector with reserved size [int].

###Constructor(array): Construct a vector with values from [array].

###Constructor(array, offset): Construct a vector from [array] range: [offset, to_array_end).

###Constructor(Uint8Array): (Not implemented yet) Construct the vector from the Uint8Array. It will assume the array has previusly been constrcted with .serialize().

###.serialize() Not implemented yet. Returns the underlying Uint8Array buffer.

###.front() Returns the first element in the vector.

###.back() Returns the last element in the vector.

###.push(Uint8) Insert [Uint8] in the back of of the vector.

###.pop() Remove last item and returns it. Alias for .pop_back()

###.reserve(Uint32) Reserve [Uint32] amount of memory.

###.capacity() Return reserved memory.

###.resize(Uint32) Resize vector size to [Uint32] elements.

###.assign(obj, offset?, length?) Assign this vector using the elements in [obj]. Obj can either be a instance of ByteVector or an object that implements obj.length and obj[N].

###.push_back(Uint8) Insert [Uint8] in the back of the vector.

###.push_front(Uint8) Insert [Uint8] in the beginning of the vector.

###.pop_back() Remove last item in the vector and returns it.

###.pop_front() Remove first element in the beginning of the vector and returns it.

###.get(pos) Return element at position [pos].

###.set(pos, value) Set element at position [pos] to value [value].

###.clear() Removes all elements from the vector.

###.size() Returns current vector size.

###.length Returns current vector size.

###.length = N Resize vector to [N] elements.

###.rawBuffer() Returns a reference to the underlying buffer.
