A number of Changes have been made to this class template in order to conform to the ACE_Hash_Map_Manager_Ex interface. All previously supported public methods are still part of this class. However, these are marked as DEPRECATED and will be removed from this class in a future version of ACE. Please migrate your code to the appropriate public methods indicated in the method deprecation comments. This class uses an ACE_Allocator to allocate memory. The user can make this a persistent class by providing an ACE_Allocator with a persistable memory pool.

Close down an RB_Tree and release dynamically allocated resources.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::bind | ( | const EXT_ID & | item, | |
const INT_ID & | int_id | |||
) | [inline] |
Associate ext_id with int_id. If ext_id is already in the tree then the <ACE_RB_Tree_Node> is not changed. Returns 0 if a new entry is bound successfully, returns 1 if an attempt is made to bind an existing entry, and returns -1 if failures occur.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::bind | ( | const EXT_ID & | ext_id, | |
const INT_ID & | int_id, | |||
ACE_RB_Tree_Node< EXT_ID, INT_ID > *& | entry | |||
) | [inline] |
Same as a normal bind, except the tree entry is also passed back to the caller. The entry in this case will either be the newly created entry, or the existing one.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::trybind | ( | const EXT_ID & | ext_id, | |
INT_ID & | int_id | |||
) | [inline] |
Associate ext_id with int_id if and only if ext_id is not in the tree. If ext_id is already in the tree then the int_id parameter is assigned the existing value in the tree. Returns 0 if a new entry is bound successfully, returns 1 if an attempt is made to bind an existing entry, and returns -1 if failures occur.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::trybind | ( | const EXT_ID & | ext_id, | |
INT_ID & | int_id, | |||
ACE_RB_Tree_Node< EXT_ID, INT_ID > *& | entry | |||

const INT_ID & | int_id | |||
) | [inline] |
Reassociate ext_id with int_id. If ext_id is not in the tree then behaves just like <bind>. Returns 0 if a new entry is bound successfully, returns 1 if an existing entry was rebound, and returns -1 if failures occur.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::rebind | ( | const EXT_ID & | ext_id, | |
const INT_ID & | int_id, | |||
ACE_RB_Tree_Node< EXT_ID, INT_ID > *& | entry | |||
) | [inline] |

const INT_ID & | int_id, | |||
INT_ID & | old_int_id | |||
) | [inline] |
Associate ext_id with int_id. If ext_id is not in the tree then behaves just like <bind>. Otherwise, store the old value of int_id into the "out" parameter and rebind the new parameters. Returns 0 if a new entry is bound successfully, returns 1 if an existing entry was rebound, and returns -1 if failures occur.
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::rebind | ( | const EXT_ID & | ext_id, | |

const INT_ID & | int_id, | |||
EXT_ID & | old_ext_id, | |||
INT_ID & | old_int_id | |||
) | [inline] |
Associate ext_id with int_id. If ext_id is not in the tree then behaves just like <bind>. Otherwise, store the old values of ext_id and int_id into the "out" parameters and rebind the new parameters. This is very useful if you need to have an atomic way of updating <ACE_RB_Tree_Nodes> and you also need full control over memory allocation. Returns 0 if a new entry is bound successfully, returns 1 if an existing entry was rebound, and returns -1 if failures occur.

INT_ID & | int_id | |||
) | [inline] |

ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::unbind | ( | const EXT_ID & | ext_id | ) | [inline] |
Unbind (remove) the ext_id from the tree. Don't return the int_id to the caller (this is useful for collections where the int_ids
are *not* dynamically allocated...)
ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::unbind | ( | const EXT_ID & | ext_id, | |
INT_ID & | int_id | |||
) | [inline] |

ACE_INLINE int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::unbind | ( | ACE_RB_Tree_Node< EXT_ID, INT_ID > * | entry | ) | [inline] |
Remove entry from tree. This method should be used with *extreme* caution, and only for optimization purposes. The node being passed in had better have been allocated by the tree that is unbinding it.

Returns the current number of nodes in the tree.

Assignment operator.
ACE_INLINE ACE_LOCK & ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::mutex | ( | void | ) | [inline] |
Returns a reference to the underlying <ACE_LOCK>. This makes it possible to acquire the lock explicitly, which can be useful in some cases if you instantiate the ACE_Atomic_Op with an ACE_Recursive_Mutex or ACE_Process_Mutex, or if you need to guard the state of an iterator.
ACE_INLINE void ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::dump | ( | void | ) | const [inline] |
Dump the state of an object.

Return reverse iterator positioned at first node in tree.
int ACE_RB_Tree< EXT_ID, INT_ID, COMPARE_KEYS, ACE_LOCK >::test_invariant | ( | void | ) | [inline] |
Tests the red-black invariant(s) throughout the whole tree.
Recursively tests the invariant red-black properties at each node of the tree. Returns 0 if invariant holds, else -1. This method is computationally expensive, and should only be called for testing purposes, and not in code that depends on the algorithmic complexity bounds provided by the other methods.

Function to dump node contents. Does nothing in its basic form, but template specialization can be used to provide definitions for various EXT_ID and INT_ID types.
Function to dump node itself. Does not show parameterized node contents in its basic form, but template specialization can be used to provide definitions for various EXT_ID and INT_ID types.
