Detailed Description

template<class T, size_t ACE_SIZE>
class ACE_Fixed_Set< T, ACE_SIZE >

Implement a simple unordered set of <T> with maximum <ACE_SIZE>.

This implementation of an unordered set uses a fixed array. It does not allow duplicate members. The set provides linear insertion/deletion operations.

Requirements and Performance Characteristics

• Internal Structure Fixed array
• 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, size_t ACE_SIZE> ACE_Fixed_Set< T, ACE_SIZE >::ACE_Fixed_Set (  void    )

Default Constructor. Creates an empy set

template<class T, size_t ACE_SIZE> ACE_Fixed_Set< T, ACE_SIZE >::ACE_Fixed_Set (  const ACE_Fixed_Set< T, ACE_SIZE > &    )

Copy constructor. Initializes a set to be a copy of the set parameter.

template<class T, size_t ACE_SIZE> ACE_Fixed_Set< T, ACE_SIZE >::~ACE_Fixed_Set (  void    )

Destructor. Destroys a set.

Member Function Documentation

template<class T, size_t ACE_SIZE> void ACE_Fixed_Set< T, ACE_SIZE >::dump (  void    )  const

Dump the state of an object.

template<class T, size_t ACE_SIZE> int ACE_Fixed_Set< T, ACE_SIZE >::find (  const T &    item )  const

Finds if item occurs in the set. Returns 0 if finds, else -1. Performs a linear find operation for the specified item.

template<class T, size_t ACE_SIZE> int ACE_Fixed_Set< T, ACE_SIZE >::insert (  const T &    new_item )

Linear time insertion of an item unique to the set. 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, size_t ACE_SIZE> ACE_INLINE int ACE_Fixed_Set< T, ACE_SIZE >::is_empty (  void    )  const

Returns 1 if the container is empty, otherwise returns 0. Performs constant time check to determine if a set is empty.

template<class T, size_t ACE_SIZE> ACE_INLINE int ACE_Fixed_Set< T, ACE_SIZE >::is_full (  void    )  const

Returns 1 if the container is full, otherwise returns 0. Performs a constant time check to see if the set is full.

template<class T, size_t ACE_SIZE> void ACE_Fixed_Set< T, ACE_SIZE >::operator= (  const ACE_Fixed_Set< T, ACE_SIZE > &    )

Assignment operator. Deep copy of one set to another.

template<class T, size_t ACE_SIZE> int ACE_Fixed_Set< T, ACE_SIZE >::remove (  const T &    item )

Linear time removal operation of an item. 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. Removal doesn't reclaim memory for the item.

template<class T, size_t ACE_SIZE> size_t ACE_Fixed_Set< T, ACE_SIZE >::size (  void    )  const

Size of the set. Returns the current size of the set.
