Detailed Description

template<class T, class C>
class ACE_Unbounded_Set_Ex< T, C >

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.

This implementation may also be parameterized with a comparator functor, which must implement bool operator () (const T&, const T&) const, returning true if the given items are equivalent. The default comparator is sufficient for objects reliably compared with operator==.

Constructor & Destructor Documentation

template<class T , class C >
ACE_Unbounded_Set_Ex< T, C >::ACE_Unbounded_Set_Ex ( ACE_Allocator alloc = 0)

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

template<class T , class C>
ACE_Unbounded_Set_Ex< T, C >::ACE_Unbounded_Set_Ex ( const C &  comparator,
ACE_Allocator alloc = 0 
)

Initialize an empty set using the allocation strategy of the user if provided, and a given comparator functor.

template<class T, class C>
ACE_Unbounded_Set_Ex< T, C >::ACE_Unbounded_Set_Ex ( const ACE_Unbounded_Set_Ex< T, C > &  us)

Copy constructor.

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

template<class T , class C >
ACE_Unbounded_Set_Ex< T, C >::~ACE_Unbounded_Set_Ex ( void  )

Destructor.

Destroy the nodes of the set.

Copy nodes into this set.

template<class T , class C >
void ACE_Unbounded_Set_Ex< T, C >::delete_nodes ( void  ) [private]

Delete all the nodes in the Set.

template<class T , class C >
void ACE_Unbounded_Set_Ex< T, C >::dump ( void  ) const

Dump the state of an object.

template<class T, class C >
int ACE_Unbounded_Set_Ex< T, C >::find ( const T &  item) const

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

template<class T, class C >
int ACE_Unbounded_Set_Ex< T, C >::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, class C >
int ACE_Unbounded_Set_Ex< T, C >::insert_tail ( const T &  item)

Insert item at the tail of the set (doesn't check for duplicates). Constant time insert at the end of the set.

template<class T , class C >
bool ACE_Unbounded_Set_Ex< T, C >::is_empty ( void  ) const [inline]

Returns true if the container is empty, otherwise returns false.

Constant time is_empty check.

template<class T , class C >
bool ACE_Unbounded_Set_Ex< T, C >::is_full ( void  ) const [inline]

Returns false.

Always returns false since the set can never fill up.

template<class T, class C>
ACE_Unbounded_Set_Ex< T, C > & ACE_Unbounded_Set_Ex< T, C >::operator= ( const ACE_Unbounded_Set_Ex< T, C > &  us)

Assignment operator.

Perform a deep copy of the rhs into the lhs.

template<class T, class C >
int ACE_Unbounded_Set_Ex< T, C >::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 , class C >
void ACE_Unbounded_Set_Ex< T, C >::reset ( void  )

Reset the ACE_Unbounded_Set_Ex to be empty.

Delete the nodes of the set.

template<class T , class C >
size_t ACE_Unbounded_Set_Ex< T, C >::size ( void  ) const

Size of the set.

Access the size of the set.
