Arrays

Constructors and Assignment

Constructor: Array<T>::Array (void)

Create an array with no elements.

Constructor: Array<T>::Array (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>::Array (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.

Operator: 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: int Array<T>::capacity (void) const

Method: int Array<T>::length (void) const

Return the length of the array.

Method: T& Array<T>::elem (int n)

Method: T& Array<T>::checkelem (int n)

Method: T& Array<T>::operator () (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: T Array<T>::elem (int n) const

Method: T Array<T>::checkelem (int n) const

Method: T Array<T>::operator () (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: T& Array<T>::xelem (int n)

Method: T Array<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: void Array<T>::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.
