22.1.1 The Array Constructor
|
|
|
|
...
|
|
|
|
The Array 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 exotic Array behaviour must include a super call to the
|
|
Array constructor to initialize subclass instances that are exotic Array
|
|
objects.
