buffer-wrapper

it make easy to use nodejs buffer when writing and reading the buffer.

it have "read offset" for reading and "length" for writing.

when read something, it increase "read offset". when write something, it increase "length"

it use big endian.

keep it mind and read below.

#usage

var BufferWp= require('buffer-wp')

var bw= new BufferWp(new Buffer(32)); bw.writeUInt16(10); bw.writeStr("abcd")

var f_buff= bw.getFitBuffer(); var f_bw= new BufferWp(f_buff);

console.log(f_bw.readUInt16()) console.log(f_bw.readStr()) console.log(f_bw.isEndOfBuffer())

//result // 10 // abcd // true
