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.

QScopedArrayPointer::QScopedArrayPointer ( D * p, QtPrivate::QScopedArrayEnsureSameType<T, D>::Type = 0 )

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.
