详细描述

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

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[]
  }

成员函数

QScopedArrayPointer::QScopedArrayPointer()

Constructs a QScopedArrayPointer instance.

void QScopedArrayPointer::swap(QScopedArrayPointer &other)

T &QScopedArrayPointer::operator[](int i)

Provides access to entry i of the scoped pointer's array of objects.

If the contained pointer is null, behavior is undefined.

参见 isNull().

const T &QScopedArrayPointer::operator[](int i) const
