Method Summary | |
def
|
++= (it : Iterable[A]) : Stack[A] |
def
|
++= (it : Iterator[A]) : Stack[A] |
override def
|
apply
(index : Int) : A
Retrieve n'th element from stack, where top of stack has index 0
|
def
|
clear
: Unit
Removes all elements from the stack. After this operation completed,
the stack will be empty.
|
override def
|
clone
: Stack[A]
This method clones the stack.
|
override def
|
isEmpty
: Boolean
Checks if the stack is empty.
|
override def
|
iterator
: 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 reversed order they were inserted into the stack
(LIFO order).
|
override def
|
length
: Int
The number of elements in the stack
|
def
|
pop
: A
Removes the top element from the stack.
|
def
|
push
(elem : A) : Stack[A]
Push an element on the stack.
|
def
|
push
(elem1 : A, elem2 : A, elems : A*) : Stack[A]
Push two or more elements onto the stack. The last element
of the sequence will be on top of the new stack.
|
def
|
pushAll
(elems : Iterator[A]) : Stack[A]
Push all elements provided by the given iterator object onto
the stack. The last element returned by the iterator
will be on top of the new stack.
|
def
|
pushAll
(elems : Traversable[A]) : Stack[A]
Push all elements provided by the given iterable object onto
the stack. The last element returned by the traversable object
will be on top of the new stack.
|
override def
|
toList
: List[A]
Creates a list of all stack elements in LIFO order.
|
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.
