This implementation of an unbounded double-linked list uses a circular linked list with a dummy node. It is pretty much like the except that it allows removing of a specific element from a specific location. Notice that this class is an implementation of a very simply data structure.is *NOT* a container class. You can use the class to implement other contains classes but it is *NOT* a general purpose container class. The parameter class *MUST* has members T* prev and T* next and users of this class are responsible to follow the general rules of using double-linked lists to maintaining the list integrities. If you need a double linked container class, check out the DLList class in this file.

Copy constructor.

Destructor.
|
|
Copy nodes from <rhs> into this list.
|
|
Removes and returns the first <item> in the list. Returns internal node's address on success, 0 if the queue was empty. This method will *not* free the internal node. Reimplemented in ACE_DLList. |
|
Delete all the nodes in the list.
|
|
Removes and returns the last <item> in the list. Returns internal nodes's address on success, 0 if the queue was empty. This method will *not* free the internal node. Reimplemented in ACE_DLList. |
|
Dump the state of an object.
Reimplemented in ACE_DLList. |
|
Get the <slot>th element in the set. Returns -1 if the element isn't in the range {0..<size> - 1}, else 0.
Reimplemented in ACE_DLList. |
|
Setup header pointer. Called after we create the head node in ctor.
|
|
Insert a <new_element> into the list. It will be added before or after <old_item>. Default is to insert the new item *after* <head_>. Return 0 if succeed, -1 if error occured. |
|
Adds <new_item> to the head of the list.Returns the new item that was inserted.
Reimplemented in ACE_DLList. |
|
Adds <new_item> to the tail of the list. Returns the new item that was inserted.
Reimplemented in ACE_DLList. |
|
Returns 1 if the container is empty, otherwise returns 0.
|
|
Returns 1 if the container is full, otherwise returns 0.

Assignment operator.

|
Use DNode address directly.
|
|
Remove an <item> from the list. Return 0 if succeed, -1 otherwise. Notice that this function checks if item is <head_> and either its <next_> or <prev_> is NULL. The function resets item's <next_> and <prev_> to 0 to prevent clobbering the double-linked list if a user tries to remove the same node again. |
|
Reset the to be empty. Notice that since no one is interested in the items within, This operation will delete all items. |
