Detailed Description

A double linked list object.

This is used as a base class for objects that will be organized through ordered double linked lists which allow convenient insertion and deletion of list members anywhere in the list.

Constructor & Destructor Documentation

Construct and add our object to an existing double linked list at end.

Parameters:
indexof linked list we are listed in.
virtual ucommon::LinkedList::~LinkedList ( ) [protected, virtual]

Delete linked list object.

If it is a member of a list of objects, then the list is reformed around us.


Member Function Documentation

void ucommon::LinkedList::enlist ( OrderedIndex index) [virtual]

Attach our object to a linked list.

The default strategy is to add to tail.

Parameters:
indexof linked list we are joining.

Reimplemented from ucommon::OrderedObject.

Attach our object to the start of a linked list though an ordered index.

If we are already attached to a list we are delisted first.

Parameters:
indexof linked list we are joining.

Reimplemented from ucommon::OrderedObject.

Attach our object to the end of a linked list though an ordered index.

If we are already attached to a list we are delisted first.

Parameters:
indexof linked list we are joining.

Reimplemented from ucommon::OrderedObject.

Get next node in the list when iterating.

Returns:
next node in list.

Reimplemented from ucommon::OrderedObject.

Definition at line 834 of file linked.h.

Get previous node in the list for reverse iteration.

Returns:
previous node in list.

Definition at line 827 of file linked.h.

virtual void ucommon::LinkedList::insert ( LinkedList object) [virtual]

Insert object, method in derived object.

Parameters:
objectto add to list.

Insert object in front of our object.

Parameters:
objectto add to list.

Insert object behind our object.

Parameters:
objectto add to list.
bool ucommon::LinkedList::isHead ( void  ) [inline]

Test if we are at the head of a list.

Returns:
true if we are the first node in a list.

Definition at line 813 of file linked.h.

bool ucommon::LinkedList::isTail ( void  ) [inline]

Test if we are at the end of a list.

Returns:
true if we are the last node in a list.

Definition at line 820 of file linked.h.

void ucommon::LinkedList::operator*= ( LinkedList object) [inline]

Insert object in list with our object.

Parameters:
objectto add to list.

Definition at line 873 of file linked.h.

void ucommon::LinkedList::operator+= ( LinkedList object) [inline]

Insert object behind our object.

Parameters:
objectto add to list.

Definition at line 859 of file linked.h.

void ucommon::LinkedList::operator-= ( LinkedList object) [inline]

Insert object in front of our object.

Parameters:
objectto add to list.
