class SynchronizedStack

class SynchronizedStack [A]
extends scala.collection.mutable.Stack[A]
with scala.ScalaObject
This is a synchronized version of the Stack[T] class. It implements a data structure which allows to store and retrieve objects in a last-in-first-out (LIFO) fashion.

Constructor Summary
def this



Def Summary
override def ++= (it: scala.Iterator[A]) : scala.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.
override def ++= (iter: scala.Iterable[A]) : scala.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.
override def += (elem: A) : scala.Unit
Pushes a single element on top of the stack.
override def clear : scala.Unit
Removes all elements from the stack. After this operation completed, the stack will be empty.
override def elements : scala.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).
override def equals (that: scala.Any) : scala.Boolean
Checks if two stacks are structurally identical.
override def hashCode : scala.Int
The hashCode method always yields an error, since it is not safe to use mutable stacks as keys in hash tables.
override def isEmpty : scala.Boolean
Checks if the stack is empty.
override def pop : A
Removes the top element from the stack.
override def push (elems: A*) : scala.Unit
Pushes a sequence of elements on top of the stack. The first element is pushed first, etc.
override def toList : scala.List[A]
Creates a list of all stack elements in FIFO order.
override def toString : java.lang.String
Returns a textual representation of a stack as a string.
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.

Def Detail
override def ++= (it: scala.Iterator[A]): scala.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

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

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

override def elements : scala.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.

override def equals (that: scala.Any): scala.Boolean
Checks if two stacks are structurally identical.
Returns:
true, iff both stacks contain the same sequence of elements.

override def hashCode : scala.Int
The hashCode method always yields an error, since it is not safe to use mutable stacks as keys in hash tables.
Returns:
never.

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

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

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

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

override def toString : java.lang.String
Returns a textual representation of a stack as a string.
Returns:
the string representation of this stack.

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
