ACE_Ordered_MultiSet< T > Class Template Reference

Implement a simple ordered multiset of {T} of unbounded size that allows duplicates. This class template requires that < operator semantics be defined for the parameterized type {T}, but does not impose any restriction on how that ordering operator is implemented.

Detailed Description

template<class T>
class ACE_Ordered_MultiSet< T >

Implement a simple ordered multiset of {T} of unbounded size that allows duplicates. This class template requires that < operator semantics be defined for the parameterized type {T}, but does not impose any restriction on how that ordering operator is implemented. The set is implemented as a linked list.

Constructor & Destructor Documentation

template<class T>
ACE_Ordered_MultiSet< T >::ACE_Ordered_MultiSet ACE_Allocator the_allocator = 0  ) 
 

Initialize the set using the allocation strategy specified. If none, use the default strategy.

template<class T>
ACE_Ordered_MultiSet< T >::ACE_Ordered_MultiSet const ACE_Ordered_MultiSet< T > &   ) 
 

Copy constructor.

Initialize the set to be a copy of the provided set.

template<class T>
ACE_Ordered_MultiSet< T >::~ACE_Ordered_MultiSet void   ) 
 

Destructor.

Delete the nodes of the set.


Member Function Documentation

template<class T>
void ACE_Ordered_MultiSet< T >::copy_nodes const ACE_Ordered_MultiSet< T > &   )  [private]
 

Copy nodes into this set.

template<class T>
void ACE_Ordered_MultiSet< T >::delete_nodes void   )  [private]
 

Delete all the nodes in the Set.

template<class T>
void ACE_Ordered_MultiSet< T >::dump void   )  const
 

Dump the state of an object.

template<class T>
int ACE_Ordered_MultiSet< T >::find const T &  item,
ITERATOR iter
const
 

Linear find operation.

Finds first occurrence of item in the multiset, using the iterator's current position as a hint to improve performance. If find succeeds, it positions the iterator at that node and returns 0, or if it cannot locate the node, it leaves the iterator alone and just returns -1.

template<class T>
int ACE_Ordered_MultiSet< T >::insert const T &  new_item,
ITERATOR iter
 

Linear time insert beginning at the point specified by the provided iterator.

Insert new_item into the ordered multiset, starting its search at the node pointed to by the iterator, and if insertion was successful, updates the iterator to point to the newly inserted node. Returns -1 if failures occur, else 0.

template<class T>
int ACE_Ordered_MultiSet< T >::insert const T &  new_item  ) 
 

Linear time, order preserving insert into the set beginning at the head.

template<class T>
int ACE_Ordered_MultiSet< T >::insert_from const T &  item,
ACE_DNode< T > *  start_position,
ACE_DNode< T > **  new_position
[private]
 

Insert item, starting its search at the position given, and if successful updates the passed pointer to point to the newly inserted item's node.

template<class T>
ACE_INLINE int ACE_Ordered_MultiSet< T >::is_empty void   )  const
 

Returns 1 if the container is empty, otherwise returns 0.

Constant time check to determine if the set is empty.

template<class T>
int ACE_Ordered_MultiSet< T >::locate const T &  item,
ACE_DNode< T > *  start_position,
ACE_DNode< T > *&  new_position
const [private]
 

Looks for first occurance of item in the ordered set, using the passed starting position as a hint: if there is such an instance, it updates the new_position pointer to point to this node and returns 0; if there is no such node, then if there is a node before where the item would have been, it updates the new_position pointer to point to this node and returns -1; if there is no such node, then if there is a node after where the item would have been, it updates the new_position pointer to point to this node (or 0 if there is no such node) and returns 1;

template<class T>
void ACE_Ordered_MultiSet< T >::operator= const ACE_Ordered_MultiSet< T > &   ) 
 

Assignment operator.

Delete the nodes in lhs, and copy the nodes from the rhs.

template<class T>
int ACE_Ordered_MultiSet< T >::remove const T &  item  ) 
 

Linear time search operation which removes the item from the set if found .

template<class T>
void ACE_Ordered_MultiSet< T >::reset void   ) 
 

Reset the ACE_Ordered_MultiSet to be empty.

Delete the nodes inside the set.

template<class T>
ACE_INLINE size_t ACE_Ordered_MultiSet< T >::size void   )  const
 

Size of the set.

Constant time check to determine the size of the set.
