Node Virtual Buffer

The virtual buffer stores buffers inside a cache and allows you to read from the "virtual" concatenated buffer in an efficient way.

Example

var VB = require('virtual-buffer');

var vb = new VB();

vb.push(new Buffer('test'));

if (vd.readable(3)) {
  console.log(vb.read(3).toString()); // "tes"
}

Api

/**
 * @class VirtualBuffer
 */
var VirtualBuffer = function()

/**
 * This pushes a buffer into the virtual buffer. Note that it uses the
 * actual instance and slices, so beware of not altering the data.
 * @param {Buffer} buffer
 */
VirtualBuffer.prototype.push(buffer)

/**
 * Check whether the buffer has "length" amount available to be read.
 * @param {int} length
 * @return {boolean}
 */
VirtualBuffer.prototype.readable(length)

/**
 * This will read from the buffer and consume the slice.
 * @param  {int} length
 * @return {Buffer}
 */
VirtualBuffer.prototype.read = function(length)
