Constructor.

Copy constructor.

Advance to the next element in the list. Return the address of the next element if there are more, 0 otherwise.
|
protected |
Retreat to the previous element in the list. Return the address of the previous element if there are more, 0 otherwise.
int ACE_Double_Linked_List_Iterator_Base< T >::done | ( | void | ) | const |
Returns 1 when all items have been seen, else 0.
|
protected |
Dump the state of an object.
|
protected |
Move to the first element of the list. Returns 0 if the list is empty, else 1.
|
protected |
Move to the last element of the list. Returns 0 if the list is empty, else 1.
int ACE_Double_Linked_List_Iterator_Base< T >::next | ( | T *& | ptr | ) | const |
Passes back the {entry} under the iterator. Returns 0 if the iteration has completed, otherwise 1
T * ACE_Double_Linked_List_Iterator_Base< T >::next | ( | void | ) | const |
|
protected |
Check if we reach the end of the list. Can also be used to get the current element in the list. Return the address of the current item if there are still elements left , 0 if we run out of element.
T & ACE_Double_Linked_List_Iterator_Base< T >::operator* | ( | void | ) | const |
STL-like iterator dereference operator: returns a reference to the node underneath the iterator.
void ACE_Double_Linked_List_Iterator_Base< T >::reset | ( | ACE_Double_Linked_List< T > & | dll | ) |
Retasks the iterator to iterate over a new Double_Linked_List. This allows clients to reuse an iterator without incurring the constructor overhead. If you do use this, be aware that if there are more than one reference to this iterator, the other "clients" may be very bothered when their iterator changes. @ Here be dragons. Comments?
ACE_Double_Linked_List_Iterator_Base< T >::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.
