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.

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 > &  fs)

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>
int ACE_Fixed_Set< T, ACE_SIZE >::is_empty ( void  ) const
inline

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>
int ACE_Fixed_Set< T, ACE_SIZE >::is_full ( void  ) const
inline

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 > &  fs)

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

Size of the set.

Returns the current size of the set.
