3.1 Constructors and Assignment
- Constructor: Array<T> (int n [, const T &val])
Create an array with n elements. If the optional argument val is supplied, the elements are initialized to val; otherwise, they are left uninitialized. If n is less than zero, the current error handler is invoked (see section Error Handling).
- Constructor: Array<T> (const Array<T> &a)
Create a copy of the Array<T> object a. Memory for the Array<T> class is managed using a reference counting scheme, so the cost of this operation is independent of the size of the array.
- Assignment on Array<T>: Array<T>& operator = (const Array<T> &a)
Assignment operator. Memory for the Array<T> class is managed using a reference counting scheme, so the cost of this operation is independent of the size of the array.
- Method on Array<T>: int capacity (void) const
- Method on Array<T>: int length (void) const
Return the length of the array.
- Method on Array<T>: T& elem (int n)
- Method on Array<T>: T& checkelem (int n)
If n is within the bounds of the array, return a reference to the element indexed by n; otherwise, the current error handler is invoked (see section Error Handling).
- Method on Array<T>: T elem (int n) const
- Method on Array<T>: T checkelem (int n) const
If n is within the bounds of the array, return the value indexed by n; otherwise, call the current error handler. See section Error Handling.
- Method on Array<T>: T& xelem (int n)
- Method on Array<T>: T xelem (int n) const
Return a reference to, or the value of, the element indexed by n. These methods never perform bounds checking.
- Method on Array<T>: void resize (int n [, const T &val])
Change the size of the array to be n elements. All elements are unchanged, except that if n is greater than the current size and the optional argument val is provided, the additional elements are initialized to val; otherwise, any additional elements are left uninitialized. In the current implementation, if n is less than the current size, the length is updated but no memory is released.
