Detailed Description
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(D *p)
Constructs a QScopedArrayPointer and stores the array of objects pointed to by p.
QScopedArrayPointer::QScopedArrayPointer()
Constructs a QScopedArrayPointer instance.
void QScopedArrayPointer::swap(QScopedArrayPointer<T, Cleanup> &other)
Swap this pointer with other.
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.
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 nullptr
behavior is undefined.
