3.1 Constructors and Assignment
— Constructor:
Array<T> (
void)
Create an array with no elements.
— 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 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 Error Handling).
— Indexing on Array<T>: T&
operator () (
int n)
— 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 Error Handling.
— Indexing on Array<T>: T
operator () (
int n)
const
— 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 (
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.
