Note: DataView is not yet implemented in Gecko. It is implemented in Chrome 9.

An ArrayBuffer is a useful object for representing an arbitrary chunk of data. In many cases, such data will be read from disk or from the network, and will not follow the alignment restrictions that are imposed on the Typed Array Views described earlier. In addition, the data will often be heterogeneous in nature and have a defined byte order.

The DataView view provides a low-level interface for reading such data from and writing it to an ArrayBuffer.



Documentation for this class was provided by MDN. */ @:native("DataView") extern class DataView extends ArrayBufferView { /** DataView DataView(ArrayBuffer buffer, optional unsigned long byteOffset, optional unsigned long byteLength);

Returns a new DataView object using the passed ArrayBuffer for its storage.

DataView DataView(
  ArrayBuffer buffer,
  optional unsigned long byteOffset,
  optional unsigned long byteLength
);
Parameters
buffer
An existing ArrayBuffer to use as the storage for the new DataView object.
byteOffset Optional
The offset, in bytes, to the first byte in the specified buffer for the new view to reference. If not specified, the view of the buffer will start with the first byte.
byteLength Optional
The number of elements in the byte array. If unspecified, length of the view will match the buffer's length.
Return value

A new DataView object representing the specified data buffer.

Exceptions thrown
INDEX_SIZE_ERR
The byteOffset and byteLength result in the specified view extending past the end of the buffer.
