Detailed Description

template<class T>
class util::Iterator< T >

Iterator is an interface for all iterable object collections.

An iterable collection may be represented as a list, hash table or whatever. The methods in this interface provide sequential acces to the data a collection contains.

Public Methods
virtual void	reset (void)=0
	Reset the iterator.
virtual T *	next (void)=0
	Get the next object in a collection.
virtual bool	hasNext (void) const=0
	Check whether the collection has more data to fetch.

Member Function Documentation

template<class T> virtual bool util::Iterator< T >::hasNext (  void    )  const [pure virtual]

Check whether the collection has more data to fetch. A call to next() should return new data until this method returns false. Implemented in util::Hashtable< key, value >, util::List< T >, util::Hashtable< int, SignalHandler * >, util::Hashtable< std::string, Serializer * >, util::Hashtable< std::string, std::string >, util::List< Sensor * >, util::List< EventListener< ClassificationEvent< T, I, C > > * >, util::List< EventListener< OptimizationEvent > * >, util::List< Node * >, util::List< Tree * >, util::List< EventListener< ClassificationEvent< T, I, int > > * >, util::List< int >, util::List< EventListener< T > * >, util::List< ThreadListener * >, util::List< Section * >, util::List< ConfusionMatrix >, util::List< EventListener< EvolutionEvent< T > > * >, and util::List< EventListener< ClassificationEvent< double, I, C > > * >.

template<class T> virtual T* util::Iterator< T >::next (  void    )  [pure virtual]

Get the next object in a collection. The collection should maintain an internal counter for sequential access. Returns: the next item in a collection or NULL if there is no more data Implemented in util::Hashtable< key, value >, util::List< T >, util::Hashtable< int, SignalHandler * >, util::Hashtable< std::string, Serializer * >, util::Hashtable< std::string, std::string >, util::List< Sensor * >, util::List< EventListener< ClassificationEvent< T, I, C > > * >, util::List< EventListener< OptimizationEvent > * >, util::List< Node * >, util::List< Tree * >, util::List< EventListener< ClassificationEvent< T, I, int > > * >, util::List< int >, util::List< EventListener< T > * >, util::List< ThreadListener * >, util::List< Section * >, util::List< ConfusionMatrix >, util::List< EventListener< EvolutionEvent< T > > * >, and util::List< EventListener< ClassificationEvent< double, I, C > > * >.

template<class T> virtual void util::Iterator< T >::reset (  void    )  [pure virtual]

Reset the iterator. Next call to next() returns the first object in a collection. Implemented in util::Hashtable< key, value >, util::List< T >, util::Hashtable< int, SignalHandler * >, util::Hashtable< std::string, Serializer * >, util::Hashtable< std::string, std::string >, util::List< Sensor * >, util::List< EventListener< ClassificationEvent< T, I, C > > * >, util::List< EventListener< OptimizationEvent > * >, util::List< Node * >, util::List< Tree * >, util::List< EventListener< ClassificationEvent< T, I, int > > * >, util::List< int >, util::List< EventListener< T > * >, util::List< ThreadListener * >, util::List< Section * >, util::List< ConfusionMatrix >, util::List< EventListener< EvolutionEvent< T > > * >, and util::List< EventListener< ClassificationEvent< double, I, C > > * >.
