The QScopedArrayPointer class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction.
A QScopedArrayPointer 是 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[] }
构造 QScopedArrayPointer 实例。
Provides access to entry i of the scoped pointer's array of objects.
If the contained pointer is
null
, behavior is undefined.
