Detailed Description

template<class T>
class ACE_Unbounded_Queue< T >

A Queue of "infinite" length.

This implementation of an unbounded queue uses a circular linked list with a dummy node.

Requirements and Performance Characteristics

Member Typedef Documentation

typedef ACE_Unbounded_Queue_Iterator<T> ACE_Unbounded_Queue< T >::ITERATOR

Constructor & Destructor Documentation

template<class T>
ACE_Unbounded_Queue< T >::ACE_Unbounded_Queue ( ACE_Allocator alloc = 0)

Construction. Use user specified allocation strategy if specified. Initialize an empty queue using the strategy provided.

template<class T>
ACE_Unbounded_Queue< T >::ACE_Unbounded_Queue ( const ACE_Unbounded_Queue< T > &  us)

Copy constructor.

Initialize the queue to be a copy of the provided queue.

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

Destructor.

Clean up the memory for the queue.

Member Function Documentation

template<class T >
ACE_Unbounded_Queue_Iterator< T > ACE_Unbounded_Queue< T >::begin ( void  )
template<class T>
void ACE_Unbounded_Queue< T >::copy_nodes ( const ACE_Unbounded_Queue< T > &  us)
protected

Copy nodes into this queue.

template<class T >
void ACE_Unbounded_Queue< T >::delete_nodes ( void  )
protected

Delete all the nodes in the queue.

template<class T>
int ACE_Unbounded_Queue< T >::dequeue_head ( T &  item)

Removes and returns the first item on the queue. Returns 0 on success, -1 if the queue was empty. Remove an item from the head of the queue.

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

Dump the state of an object.

template<class T >
ACE_Unbounded_Queue_Iterator< T > ACE_Unbounded_Queue< T >::end ( void  )
template<class T>
int ACE_Unbounded_Queue< T >::enqueue_head ( const T &  new_item)

Adds new_item to the head of the queue. Returns 0 on success, -1 on failure. Insert an item at the head of the queue.

template<class T>
int ACE_Unbounded_Queue< T >::enqueue_tail ( const T &  new_item)

Adds new_item to the tail of the queue. Returns 0 on success, -1 on failure. Insert an item at the end of the queue.

template<class T>
int ACE_Unbounded_Queue< T >::get ( T *&  item,
size_t  slot = 0 
) const

Get the slot th element in the set. Returns -1 if the element isn't in the range {0..cur_size_ - 1}, else 0. Find the item in the queue between 0 and the provided index of the queue.

template<class T >
bool ACE_Unbounded_Queue< T >::is_empty ( void  ) const
inline

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

Constant time check to see if the queue is empty.

template<class T >
bool ACE_Unbounded_Queue< T >::is_full ( void  ) const
inline

Returns 0.

The queue cannot be full, so it always returns 0.

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

Assignment operator.

Perform a deep copy of rhs.

template<class T >
void ACE_Unbounded_Queue< T >::reset ( void  )

Reset the ACE_Unbounded_Queue to be empty and release all its dynamically allocated resources. Delete the queue nodes.

template<class T>
int ACE_Unbounded_Queue< T >::set ( const T &  item,
size_t  slot 
)

Set the slot th element of the queue to item.

Set the slot th element in the set. Will pad out the set with empty nodes if slot is beyond the range {0..cur_size_ - 1}. Returns -1 on failure, 0 if slot isn't initially in range, and 0 otherwise.

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

The number of items in the queue.

Return the size of the queue.
