Method Detail

self

  abstract def self: Stack[A]

apply

  override def apply(n: Int): A
Access element number n.
Returns:
the element at index n.

length

  override def length: Int
Returns the length of this stack.

isEmpty

  override def isEmpty: Boolean
Checks if the stack is empty.
Returns:
true, iff there is no element on the stack

+=

  override def +=(elem: A): Unit
Pushes a single element on top of the stack.
Parameters:
elem - the element to push onto the stack

++=

  override def ++=(iter: Iterable[A]): Unit
Pushes all elements provided by an Iterable object on top of the stack. The elements are pushed in the order they are given out by the iterator.
Parameters:
iter - an iterable object

++=

  override def ++=(it: Iterator[A]): Unit
Pushes all elements provided by an iterator on top of the stack. The elements are pushed in the order they are given out by the iterator.
Parameters:
iter - an iterator

push

  override def push(elems: A*): Unit
Pushes a sequence of elements on top of the stack. The first element is pushed first, etc.
Parameters:
elems - a sequence of elements

top

  override def top: A
Returns the top element of the stack. This method will not remove the element from the stack. An error is signaled if there is no element on the stack.
Returns:
the top element

pop

  override def pop: A
Removes the top element from the stack.

clear

  override def clear: Unit
Removes all elements from the stack. After this operation completed, the stack will be empty.

elements

  override def elements: Iterator[A]
Returns an iterator over all elements on the stack. This iterator is stable with respect to state changes in the stack object; i.e. such changes will not be reflected in the iterator. The iterator issues elements in the order they were inserted into the stack (FIFO order).
Returns:
an iterator over all stack elements.

toList

  override def toList: List[A]
Creates a list of all stack elements in FIFO order.
Returns:
the created list.

clone

  override def clone(): Stack[A]
This method clones the stack.
Returns:
a stack with the same elements.
