Uint8Array

extern class js.html.Uint8Arrayextends ArrayBufferViewAvailable in js

The UInt8Array type represents an array of 8-bit unsigned integers.

Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).



Documentation for this class was provided by MDN.
var length(default,null) : IntThe number of entries in the array; for these 8-bit values, this is the same as the size of the array in bytes. Read only. function new( buffer : ArrayBuffer, ?byteOffset : Int, ?length : Int ) : Void
Note: In these methods, TypedArray represents any of the typed array object types.
Uint8Array Uint8Array(unsigned long length);
Uint8Array Uint8Array(TypedArray array);
Uint8Array Uint8Array(sequence<type> array);
Uint8Array Uint8Array(ArrayBuffer buffer, optional unsigned long byteOffset, optional unsigned long length);

Returns a new Uint8Array object.

Uint8Array Uint8Array(
  unsigned long length
);

Uint8Array Uint8Array(
  TypedArray array
);

Uint8Array Uint8Array(
  sequence<type> array
);

Uint8Array Uint8Array(
  ArrayBuffer buffer,
  optional unsigned long byteOffset,
  optional unsigned long length
);
Parameters
length
The number of elements in the byte array. If unspecified, length of the array view will match the buffer's length.
array
An object of any of the typed array types (such as Int32Array), or a sequence of objects of a particular type, to copy into a new ArrayBuffer. Each value in the source array is converted to an 8-bit unsigned integer before being copied into the new array.
buffer
An existing ArrayBuffer to use as the storage for the new Uint8Array object.
byteOffset
The offset, in bytes, to the first byte in the specified buffer for the new view to reference. If not specified, the Uint8Array's view of the buffer will start with the first byte.
Return value

A new Uint8Array object representing the specified data buffer.

function set( array : Array<Int>, ?offset : Int ) : Void

Sets multiple values in the typed array, reading input values from a specified array.

Parameters
array
An array from which to copy values. All values from the source array are copied into the target array, unless the length of the source array plus the offset exceeds the length of the target array, in which case an exception is thrown. If the source array is a typed array, the two arrays may share the same underlying ArrayBuffer; the browser will intelligently copy the source range of the buffer to the destination range.
offset Optional
The offset into the target array at which to begin writing values from the source array. If you omit this value, 0 is assumed (that is, the source array will overwrite values in the target array starting at index 0).
function subarray( start : Int, ?end : Int ) : Uint8Array static inline var BYTES_PER_ELEMENT : IntThe size, in bytes, of each array element.
