virtual bool	addAll (const Collection< E > &collection)
	Adds all of the elements in the specified collection to this collection.The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified collection is this collection, and this collection is nonempty.)

Detailed Description

template<typename E>
class decaf::util::LinkedList< E >

A complete implementation of the List interface using a doubly linked list data structure.

This class also implements the Deque interface providing a common interface for additions into the list at the front and end as well as allowing insertions anywhere in between. This class can be used then to implement other data structures such as Stacks, Queue's or double ended Queue's.

The operations on this List object that index a particular element involve iterating over the links of the list from beginning to end, starting from whichever end is closer to the location the operation is to be performed on.

Member Function Documentation

template<typename E>

virtual bool decaf::util::LinkedList< E >::add ( const E &  value )

inlinevirtual

Returns true if this collection changed as a result of the call.

(Returns false if this collection does not permit duplicates and already contains the specified element.)

Collections that support this operation may place limitations on what elements may be added to this collection. In particular, some collections will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. Collection classes should clearly specify in their documentation any restrictions on what elements may be added.

If a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). This preserves the invariant that a collection always contains the specified element after this call returns.

For non-pointer values, i.e. class instances or string's the object will be copied into the collection, thus the object must support being copied, must not hide the copy constructor and assignment operator.

Parameters

value

The reference to the element to add to this Collection.

Returns

true if the element was added to this Collection.

Exceptions

UnsupportedOperationExceptio	if this is an unmodifiable collection.
NullPointerException	if the Collection is a container of pointers and does not allow NULL values.
IllegalArgumentException	if some property of the element prevents it from being added to this collection
IllegalStateException	if the element cannot be added at this time due to insertion restrictions.

Reimplemented from decaf::util::AbstractList< E >.

template<typename E>

virtual void decaf::util::LinkedList< E >::add ( int index  , const E &  element  )

inlinevirtual

Parameters

index	The index at which the specified element is to be inserted.
element	The element to be inserted in this List.

Exceptions

IndexOutOfBoundsException	if the index is greater than size of the List.

NullPointerException	if the Collection is a container of pointers and does not allow NULL values.
IllegalArgumentException	if some property of the element prevents it from being added to this collection
IllegalStateException	if the element cannot be added at this time due to insertion restrictions.

This implementation first gets a list iterator pointing to the indexed element (with listIterator(index)). Then, it inserts the specified element with ListIterator.add.

Unlike the addLast method that throws an exception if it cannot insert the element due to capacity restrictions etc this method returns false if it cannot insert the element.

Parameters

element

The element to add to this Deque.

Returns

true if the element was added, false otherwise.

Exceptions

NullPointerException	if the specified element is NULL and this deque is a Collection of pointers and does not permit null elements.
IllegalArgumentException	if some property of the specified element prevents it from being added to this deque.

virtual bool decaf::util::LinkedList< E >::peek ( E &  result ) const

inlinevirtual

Gets but not removes the element in the head of the queue.

The result if successful is assigned to the result parameter.

Parameters

result

Reference to an instance of the contained type to assigned the removed value to.

Returns

true if the element at the head of the queue was removed and assigned to the result parameter.

Implements decaf::util::Queue< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::peekFirst ( E &  value ) const

inlinevirtual

Retrieves the first element contained in this Deque and assigns its value to the reference value passed the value however is not removed from the Deque.

If this call is successful it returns true. Unlike getFirst this method does not throw an exception if the Deque is empty.

Returns

true if an element was assigned to the reference passed, false otherwise.

Implements decaf::util::Deque< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::peekLast ( E &  value ) const

inlinevirtual

Retrieves the last element contained in this Deque and assigns its value to the reference value passed the value however is not removed from the Deque.

If this call is successful it returns true. Unlike getLast this method does not throw an exception if the Deque is empty.

Returns

true if an element was assigned to the reference passed, false otherwise.

Implements decaf::util::Deque< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::poll ( E &  result )

inlinevirtual

Gets and removes the element in the head of the queue.

If the operation succeeds the value of the element at the head of the Queue is assigned to the result parameter and the method returns true. If the operation fails the method returns false and the value of the result parameter is undefined.

Parameters

result

Reference to an instance of the contained type to assigned the removed value to.

Returns

true if the element at the head of the queue was removed and assigned to the result parameter.

Implements decaf::util::Queue< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::pollFirst ( E &  element )

inlinevirtual

Removes the first element from the Deque assigns it to the element reference passed.

Parameters

element

Reference to an variable that can be assigned the value of the head of this Deque.

Returns

true if an element was available to remove, false otherwise.

Implements decaf::util::Deque< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::pollLast ( E &  element )

inlinevirtual

Removes the last element from the Deque assigns it to the element reference passed.

Parameters

element

Reference to an variable that can be assigned the value of the tail of this Deque.

Returns

true if an element was available to remove, false otherwise.

Implements decaf::util::Deque< E >.

template<typename E>

virtual E decaf::util::LinkedList< E >::pop ( )

inlinevirtual

Treats this Deque as a stack and attempts to pop an element off the top.

If there's no element to pop then a NuSuchElementException is thrown, otherwise the top element is removed and assigned to the reference passed.

This operation performs the same basic function as the removeFirst method.

Returns

the element at the front of this deque which would be the top of a stack.

Exceptions

NoSuchElementException

if there is nothing on the top of the stack.

Implements decaf::util::Deque< E >.

template<typename E>

virtual void decaf::util::LinkedList< E >::push ( const E &  element )

inlinevirtual

Pushes an element onto the stack represented by this deque (in other words, at the head of this deque) if it is possible to do so immediately without violating capacity restrictions, otherwise it throwing an IllegalStateException if no space is currently available.

This method performs the same basic operation as the addFirst method.

Parameters

element

The element to be pushed onto the Deque.

Exceptions

IllegalStateException	if the element cannot be added at this time due to capacity restrictions
NullPointerException	if the specified element is NULL and this deque is a Collection of pointers and does not permit null elements.
IllegalArgumentException	if some property of the specified element prevents it from being added to this deque.

Implements decaf::util::Deque< E >.

template<typename E>

virtual bool decaf::util::LinkedList< E >::remove ( const E &  value )

inlinevirtual

Removes a single instance of the specified element from the collection.More formally, removes an element e such that (value == NULL ? e == NULL : value == e), if this collection contains one or more such elements. Returns true if this collection contained the specified element (or equivalently, if this collection changed as a result of the call).

Parameters

value

The reference to the element to remove from this Collection.

Returns

true if the collection was changed, false otherwise.

Exceptions

UnsupportedOperationExceptio	if this is an unmodifiable collection.
NullPointerException	if the Collection is a container of pointers and does not allow NULL values.

This implementation iterates over the collection looking for the specified element. If it finds the element, it removes the element from the collection using the iterator's remove method.Note that this implementation throws an UnsupportedOperationException if the iterator returned by this collection's iterator method does not implement the remove method and this collection contains the specified object.
