24.2.2 The DataView Constructor
|
|
|
|
...
|
|
|
|
The DataView constructor is designed to be subclassable. It may be used as the
|
|
value of an extends clause of a class definition. Subclass constructors that
|
|
intend to inherit the specified DataView behaviour must include a super call
|
|
to the DataView constructor to create and initialize subclass instances with
|
|
the internal state necessary to support the DataView.prototype built-in
|
|
methods.
