Javascript Uint16Array Type

Introduction

A Uint16Array object describes an array-like view of an underlying binary data buffer.

The constructors are listed as follows:

new Uint16Array();
new Uint16Array(length);
new Uint16Array(typedArray);
new Uint16Array(object);
new Uint16Array(buffer [, byteOffset [, length]]);

Parameter	Optional	Meaning
length	Required	an internal array buffer is created of size `length` multiplied by BYTES_PER_ELEMENT bytes.
typedArray	Required	the typedArray is copied into a new typed array.
object	Required	use the Uint16Array.`from()` method.
buffer	Required	create from buffer
byteOffset	optional	offset to start
length	optional	length to copy

Property access

You can reference elements in the array using standard array index syntax.

var int16 = new Uint16Array(2);
int16[0] = 42;/*from   ww  w  .j  a  v  a2s. co  m*/
console.log(int16[0]); // 42

Type	Value Range	Size in bytes	Description	Equivalent C type
Uint16Array	0 to 65535	2	16-bit unsigned integer	uint16_t
