) -> JSObjectRefJSBase and JSTypedArray and JSValueRef only.Expand description
Creates a JavaScript Typed Array object from an existing JavaScript Array Buffer object with the given offset and length.
Parameter ctx: The execution context to use.
Parameter arrayType: A value identifying the type of array to create. If arrayType is kJSTypedArrayTypeNone or kJSTypedArrayTypeArrayBuffer then NULL will be returned.
Parameter buffer: An Array Buffer object that should be used as the backing store for the created JavaScript Typed Array object.
Parameter byteOffset: The byte offset for the created Typed Array. byteOffset should aligned with the element size of arrayType.
Parameter length: The number of elements to include in the Typed Array.
Parameter exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.
Returns: A JSObjectRef that is a Typed Array or NULL if there was an error. The backing store of the Typed Array will be buffer.
