## 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[]
     }

## Member Function Documentation

### QScopedArrayPointer::QScopedArrayPointer ( T * p = 0 )

Constructs this QScopedArrayPointer instance and sets its pointer to p.

### 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.
