Class FIFOList<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

java.util.Vector<E>

eu.simuline.util.FIFOList<E>

Type Parameters:

E - the class of the elements of this list.

All Implemented Interfaces:

Serializable, Cloneable, Iterable<E>, Collection<E>, List<E>, Queue<E>, RandomAccess

public final class FIFOList<E>
extends Vector<E>
implements Queue<E>

The FIFOList class represents a first-in-first-out (FIFO) stack of objects. The usual push and pop operations are provided, as well as a method to peek at the top item on the stack, a method to test for whether the stack is empty, and a method to search the stack for an item and discover how far it is from the top.

When a stack is first created, it contains no items.

FIFOList

public FIFOList()

Creates an empty FIFOList.

FIFOList

protected FIFOList(Collection<? extends E> coll)

Constructs a vector containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Parameters:

coll - the collection whose elements are to be placed into this FIFOList.

Throws:

NullPointerException - if the specified collection is null.

Method Detail

create

public static <E> FIFOList<E> create()

create

public static <E> FIFOList<E> create(Collection<? extends E> coll)

offer

public boolean offer(E item)

Constructs a vector.

Specified by:

offer in interface Queue<E>

Parameters:

item - the element to insert.

Returns:

true since nothing can prevent the item from being inserted.

Specified by:

poll in interface Queue<E>

remove

public E remove()

Specified by:

remove in interface Queue<E>

peek

public E peek()

Specified by:

peek in interface Queue<E>

element

public E element()

Specified by:

element in interface Queue<E>
