详细描述

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[]
}

template <typename D, if_same_type<D>> QScopedArrayPointer:: QScopedArrayPointer ( D * p )

Constructs a QScopedArrayPointer and stores the array of objects pointed to by p .

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 nullptr , behavior is undefined.

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 nullptr behavior is undefined.
