Int8Array Interface

The Int8Array type represents an array of twos-complement 8-bit signed 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).

from MDN

Extends

List<E>, ArrayBufferView

Constructors

Code new Int8Array.fromBuffer(ArrayBuffer buffer, [int byteOffset, int length]) #

Int8Array.fromBuffer(ArrayBuffer buffer, [int byteOffset, int length]);

Code new Int8Array.fromList(List<int> list) #

Int8Array.fromList(List<int> list);

Code new Int8Array(int length) #

Int8Array(int length);

Static Fields

Code final int BYTES_PER_ELEMENT # 

static final int BYTES_PER_ELEMENT = 1;

Methods

Code void setElements(Object array, [int offset]) #

void setElements(Object array, [int offset]);

Code Int8Array subarray(int start, [int end]) #

Returns a new Int8Array view on the ArrayBuffer store for this Int8Array object.

Parameters
begin
The offset to the first element in the array to be referenced by the new Int8Array object.
end Optional
The offset to the last element in the array to be referenced by the new Int8Array object; if not specified, all elements from the one specified by begin to the end of the array are included in the new view.
Notes

The range specified by begin and end is clamped to the valid index range for the current array; if the computed length of the new array would be negative, it's clamped to zero. If either begin or end is negative, it refers to an index from the end of the array instead of from the beginning.

Note: Keep in mind that this is creating a new view on the existing buffer; changes to the new object's contents will impact the original object and vice versa.
from MDN
Int8Array subarray(int start, [int end]);

Fields

Code final int length #

The 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.
from MDN
final int length;
