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_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::ACE_RB_Tree_Iterator_Base ( const ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  iter)

Copy constructor.

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 ( void  )
inlineprotected

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.

Destructor.

inline

Comparison operator: returns 1 if the iterators point to different positions, otherwise 0.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
ACE_RB_Tree_Node< EXT_ID, INT_ID > & ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::operator* ( void  ) const
inline

STL-like iterator dereference operator: returns a reference to the node underneath the iterator.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
ACE_RB_Tree_Node< EXT_ID, INT_ID > * ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::operator-> ( void  ) const
inline

STL-like iterator dereference operator: returns a pointer to the node underneath the iterator.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
void ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::operator= ( const ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  iter)

Assignment operator: copies both the tree reference and the position in the tree.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
bool ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::operator== ( const ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > &  rbt) const
inline

Comparison operator: returns 1 if both iterators point to the same position, otherwise 0.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
int ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::reverse_i ( void  )
inlineprotected

Move back by one element in the tree. Returns 0 when there are no more elements in the tree, otherwise 1.

template<class EXT_ID , class INT_ID , class COMPARE_KEYS , class ACE_LOCK >
const ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK > & ACE_RB_Tree_Iterator_Base< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::tree ( void  )
inline
