Detailed Description

template<typename T, typename Cleanup = QScopedPointerArrayDeleter<T>>
class QScopedArrayPointer< T, Cleanup >

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

\inmodule QtCore

Since

4.6 \reentrant

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

operator[]() [1/2]

template<typename T , typename Cleanup = QScopedPointerArrayDeleter<T>>

template< typename T, typename Cleanup > T * QScopedArrayPointer< T, Cleanup >::operator[] ( int  i )

inline

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

If the contained pointer is \nullptr, behavior is undefined.
