Detailed Description

template<class EXT_ID, class INT_ID, class COMPARE_KEYS, class ACE_LOCK>
class ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >

Implements a common base class for iterators for a Red-Black Tree ADT.


Constructor & Destructor Documentation

template<class EXT_ID, class INT_ID, class COMPARE_KEYS, class ACE_LOCK>
ACE_INLINE ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::ACE_RB_Tree_Iterator_Base void   )  [protected]
 

Create the singular iterator. No valid iterator can be equal to it, it is illegal to dereference a singular iterator, etc. etc.

template<class EXT_ID, class INT_ID, class COMPARE_KEYS, class ACE_LOCK>
ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::ACE_RB_Tree_Iterator_Base const ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  tree,
int  set_first
[protected]
 

Constructor. Takes an ACE_RB_Tree over which to iterate, and an integer indicating (if non-zero) to position the iterator at the first element in the tree (if this integer is 0, the iterator is positioned at the last element in the tree).

template<class EXT_ID, class INT_ID, class COMPARE_KEYS, class ACE_LOCK>
ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::ACE_RB_Tree_Iterator_Base const ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  tree,
ACE_RB_Tree_Node< EXT_ID, INT_ID > *  entry
[protected]
 

Constructor. Takes an ACE_RB_Tree over which to iterate, and a pointer to a node in the tree.

template<class EXT_ID, class INT_ID, class COMPARE_KEYS, class ACE_LOCK>
ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::ACE_RB_Tree_Iterator_Base const EXT_ID &  key,
ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  tree
[protected]
 

Constructor. Takes an ACE_RB_Tree over which to iterate, and a key. The key must come first to distinguish the case of EXT_ID == int.
