The current implementation is not entirely correct yet. Two classes have
been added:
- TypedArrayConstructor, which the various typed array constructors now
inherit from. Calling or constructing this class (from JS, that is)
directly is not possible, we might want to move this abstract class
functionality to NativeFunction at a later point.
- TypedArrayPrototype, which the various typed array prototypes now have
as their own prototype. This will be the place where most of the
functionality is being shared.
Relevant parts from the spec:
22.2.1 The %TypedArray% Intrinsic Object
The %TypedArray% intrinsic object:
- is a constructor function object that all of the TypedArray
constructor objects inherit from.
- along with its corresponding prototype object, provides common
properties that are inherited by all TypedArray constructors and their
instances.
22.2.2 Properties of the %TypedArray% Intrinsic Object
The %TypedArray% intrinsic object:
- has a [[Prototype]] internal slot whose value is %Function.prototype%.
22.2.2.3 %TypedArray%.prototype
The initial value of %TypedArray%.prototype is the %TypedArray%
prototype object.
22.2.6 Properties of the TypedArray Constructors
Each TypedArray constructor:
- has a [[Prototype]] internal slot whose value is %TypedArray%.
22.2.6.2 TypedArray.prototype
The initial value of TypedArray.prototype is the corresponding
TypedArray prototype intrinsic object (22.2.7).
22.2.7 Properties of the TypedArray Prototype Objects
Each TypedArray prototype object:
- has a [[Prototype]] internal slot whose value is %TypedArray.prototype%.
22.2.7.2 TypedArray.prototype.constructor
The initial value of a TypedArray.prototype.constructor is the
corresponding %TypedArray% intrinsic object.
