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.

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 > &  bs)

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 >
int ACE_Bounded_Set< T >::is_empty ( void  ) const
inline

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 >
int ACE_Bounded_Set< T >::is_full ( void  ) const
inline

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 > &  bs)

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.
