Detailed Description

template<class T>
class ACE_Unbounded_Set< T >

Implement a simple unordered set of <t> of unbounded size.

This implementation of an unordered set uses a circular linked list with a dummy node. This implementation does not allow duplicates, but it maintains FIFO ordering of insertions.

Requirements and Performance Characteristics

• Internal Structure Circular linked list
• Duplicates allowed? No
• Random access allowed? No
• Search speed Linear
• Insert/replace speed Linear
• Iterator still valid after change to container? Yes
• Frees memory for removed elements? Yes
• Items inserted by Value
• Requirements for contained type
  1. Default constructor
  2. Copy constructor
  3. operator=
  4. operator==

Constructor & Destructor Documentation

template<class T> ACE_Unbounded_Set< T >::ACE_Unbounded_Set (  ACE_Allocator *  alloc = 0  )

Initialize an empty set using the allocation strategy of the user if provided.

template<class T> ACE_Unbounded_Set< T >::ACE_Unbounded_Set (  const ACE_Unbounded_Set< T > &   )

Copy constructor. Initialize this set to be an exact copy of the set provided.

template<class T> ACE_Unbounded_Set< T >::~ACE_Unbounded_Set (  void   )

Destructor. Destroy the nodes of the set.

---

Member Function Documentation

template<class T> ACE_Unbounded_Set_Iterator< T > ACE_Unbounded_Set< T >::begin (  void   )

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

Copy nodes into this set.

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

Delete all the nodes in the Set.

template<class T> void ACE_Unbounded_Set< T >::dump (  void   )  const

Dump the state of an object.

template<class T> ACE_Unbounded_Set_Iterator< T > ACE_Unbounded_Set< T >::end (  void   )

template<class T> int ACE_Unbounded_Set< T >::find (  const T &  item  )  const

Performs a linear find operation.

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

Linear insertion of an item. Insert new_item into the set (doesn't allow duplicates). Returns -1 if failures occur, 1 if item is already present, else 0.

template<class T> int ACE_Unbounded_Set< T >::insert_tail (  const T &  item  )

Constant time insert at the end of the set.

template<class T> ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int ACE_Unbounded_Set< T >::is_empty (  void   )  const

Returns 1 if the container is empty, otherwise returns 0. Constant time is_empty check.

template<class T> ACE_INLINE int ACE_Unbounded_Set< T >::is_full (  void   )  const

Returns 0. Always returns 0 since the set can never fill up.

template<class T> ACE_Unbounded_Set< T > & ACE_Unbounded_Set< T >::operator= (  const ACE_Unbounded_Set< T > &   )

Assignment operator. Perform a deep copy of the rhs into the lhs.

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

Linear remove operation. Remove first occurrence of item from the set. Returns 0 if it removes the item, -1 if it can't find the item, and -1 if a failure occurs.

template<class T> void ACE_Unbounded_Set< T >::reset (  void   )

Reset the <ace_unbounded_set> to be empty. Delete the nodes of the set.

template<class T> ACE_BEGIN_VERSIONED_NAMESPACE_DECL size_t ACE_Unbounded_Set< T >::size (  void   )  const

Size of the set. Access the size of the set.
