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

Since: | Qt 4.6 |
Inherits: | QScopedPointer |
This class was introduced in Qt 4.6.
Note: All functions in this class are reentrant.

const T & | operator[](int i) const |
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[] }
Constructs a QScopedArrayPointer and stores the array of objects pointed to by p.
Constructs a QScopedArrayPointer instance.
Swap this pointer with other.
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().
