## Detailed Description

The QScopedArrayPointer class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction.

A QScopedArrayPointer is a QScopedPointer that defaults to deleting the object it is pointing to with the delete[] operator. It also features operator[] for convenience, so we can write:

      void foo()
      {
          QScopedArrayPointer<int> i(new int[10]);
          i[2] = 42;
          ...
          return; // our integer array is now deleted using delete[]
      }

### QScopedArrayPointer::QScopedArrayPointer()

Constructs a QScopedArrayPointer instance.

### T &QScopedArrayPointer::operator[](int i)

Provides access to entry i of the scoped pointer's array of objects.

If the contained pointer is `null`, behavior is undefined.

See also isNull().

### const T &QScopedArrayPointer::operator[](int i) const

Provides access to entry i of the scoped pointer's array of objects.

If the contained pointer is `null`, behavior is undefined.
