Detailed Description

template<class T>
class ACE_Bounded_Set< T >

Implement a simple unordered set of <T> with maximum set at creation time.

This implementation of an unordered set uses a Bounded array. This implementation does not allow duplicates. It provides linear insert/remove/find operations. Insertion/removal does not invalidate iterators, but caution should be taken to ensure expected behavior. Once initialized, the object has a maximum size which can only be increased by the assignment of another larger Bounded_Set.

Requirements and Performance Characteristics

• Internal Structure Bounded array which can grow via assignment
• 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? No
• 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_Bounded_Set< T >::ACE_Bounded_Set (  void    )

Construct a Bounded_Set using the default size. The default constructor initializes the Bounded_Set to a maximum size specified by the DEFAULT_SIZE.

template<class T> ACE_Bounded_Set< T >::ACE_Bounded_Set (  size_t    size )

Construct a Bounded_Set with the provided sizeB. Initialize the Bounded_Set to have a maximum size equal to the size parameter specified.

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

Construct a Bounded_Set that is a copy of the provides Bounded_Set. Initialize the Bounded_Set to be a copy of the Bounded_Set parameter.

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

Destructor. Clean up the underlying dynamically allocated memory that is used by the Bounded_Set.

Member Function Documentation

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

Dump the state of an object.

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

Finds if item occurs in the set. Returns 0 if finds, else -1. find preforms a linear search for <item> and returns 0 on successful find and -1 otherwise.

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

Inserts a new element unique to the set. Insert new_item into the set (doesn't allow duplicates) in linear time. Returns -1 if failures occur, 1 if item is already present, else 0.

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

Returns 1 if the container is empty, otherwise returns 0. A constant time check is performed to determine if the Bounded_Set is empty.

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

Returns 1 if the container is full, otherwise returns 0. Performs a constant time check to determine if the Bounded_Set is at capacity.

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

Assignment operator. The assignment will make a deep copy of the Bounded_Set provided. If the rhs has more elements than the capacity of the lhs, then the lhs will be deleted and reallocated to accomadate the larger number of elements.

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

Finds the specified element and removes it from the set. 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. The linear remove operation does not reclaim the memory associated with the removed item.

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

Size of the set. Returns a size_t representing the current size of the set.
