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()
Constructs a QScopedArrayPointer instance.
T &QScopedArrayPointer::operator[](qsizetype i)
Provides access to entry i of the scoped pointer's array of objects.
If the contained pointer is nullptr
, behavior is undefined.
Note: In Qt versions prior to 6.5, i was of type int
, not qsizetype
, possibly causing truncation on 64-bit platforms.
