Member Function Documentation

template<class T> int ACE_Unbounded_Queue_Iterator< T >::advance (  void   )

Move forward by one element in the set. Returns 0 when all the items in the queue have been seen, else 1. Definition at line 396 of file Unbounded_Queue.cpp. Referenced by ACE_ARGV_T< CHAR_TYPE >::create_buf_from_queue(), ACE_Unbounded_Queue< T >::dump(), ACE_Stats::mean(), ACE_Service_Gestalt::process_commandline_directives(), ACE_Service_Gestalt::process_directives(), ACE_Notification_Queue::reset(), and ACE_Stats::std_dev(). { // ACE_TRACE ("ACE_Unbounded_Queue_Iterator<T>::advance"); this->current_ = this->current_->next_; return this->current_ != this->queue_.head_; }

template<class T> int ACE_Unbounded_Queue_Iterator< T >::done (  void   )  const

Returns 1 when all items have been seen, else 0. Definition at line 412 of file Unbounded_Queue.cpp. References ACE_TRACE. Referenced by ACE_ARGV_T< CHAR_TYPE >::create_buf_from_queue(), ACE_Stats::mean(), and ACE_Stats::std_dev(). { ACE_TRACE ("ACE_Unbounded_Queue_Iterator<T>::done"); return this->current_ == this->queue_.head_; }

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

Dump the state of an object. Definition at line 380 of file Unbounded_Queue.cpp. { #if defined (ACE_HAS_DUMP) // ACE_TRACE ("ACE_Unbounded_Queue_Iterator<T>::dump"); #endif /* ACE_HAS_DUMP */ }

template<class T> int ACE_Unbounded_Queue_Iterator< T >::first (  void   )

Move to the first element in the queue. Returns 0 if the queue is empty, else 1. Definition at line 404 of file Unbounded_Queue.cpp. { // ACE_TRACE ("ACE_Unbounded_Queue_Iterator<T>::first"); this->current_ = this->queue_.head_->next_; return this->current_ != this->queue_.head_; }

template<class T> int ACE_Unbounded_Queue_Iterator< T >::next (  T *&  next_item  )

Pass back the next_item that hasn't been seen in the queue. Returns 0 when all items have been seen, else 1. Definition at line 420 of file Unbounded_Queue.cpp. Referenced by ACE_ARGV_T< CHAR_TYPE >::create_buf_from_queue(), ACE_Unbounded_Queue< T >::dump(), ACE_Stats::mean(), ACE_Service_Gestalt::process_commandline_directives(), ACE_Service_Gestalt::process_directives(), ACE_Notification_Queue::reset(), and ACE_Stats::std_dev(). { // ACE_TRACE ("ACE_Unbounded_Queue_Iterator<T>::next"); if (this->current_ == this->queue_.head_) return 0; else { item = &this->current_->item_; return 1; } }
