The Buffer with Array API

Example

const ba = require('buffer-array')

var buf = ba(4)

buf.push(new Buffer([0, 0x0a]))
var x = buf.popInt16BE() // x == 10

API

  • constructor(data: Buffer): BufferArray
  • constructor(size: Number): BufferArray

Create new instance of buffer-array with fixed-size buffer

  • seek(pos: Number): void
  • seek(): Number

Set / get current pointer position.

var packet = ba(38)
packet.pushInt32BE(640)
packet.seek() //  == 4
packet.length //  == 38  

length: Number

Get length of the internal buffer

clear(): void

Remove all written data and set pointer position to 0.

toBuffer(): Buffer

Get internal buffer (not a copy)

push(data: Buffer): bool

Write buffer data to the end

  • pushDoubleBE(data: Number): bool
  • pushDoubleLE(data: Number): bool
  • pushFloatBE(data: Number): bool
  • pushFloatLE(data: Number): bool
  • pushInt32BE(data: Number): bool
  • pushInt32LE(data: Number): bool

  • pushUInt32LE(data: Number): bool
  • pushUInt16BE(data: Number): bool
  • pushUInt16LE(data: Number): bool
  • pushInt8(data: Number): bool
  • pushUInt8(data: Number): bool

  • popUInt16BE(): Number
  • popUInt16LE(): Number
  • popInt8(): Number
  • popUInt8(): Number

Read fixed-size number from the end. Return undefined if out of bounds.

  • shift(size: Number): Buffer
  • read(size: Number): Buffer

Read size bytes from the beginning and return buffer. Return undefined if out of bounds.
