Iterator Class Reference

#include <coherence/util/Iterator.hpp>

Inherits Object.

Inherited by ListIterator [virtual], Muterator [virtual], and EndIterator [virtual].

Detailed Description

An object that implements the Iterator interface generates series of Object::Holders, one at a time.

Successive calls to next() return successive elements of the series.

For example, to print all elements of a collection hCol:

 for (Iterator::Handle hIter = hCol->iterator(); hIter->hasNext(); )
     {
     std::cout << hIter->next() << std::endl;
     }


Public Types
typedef spec::Handle	Handle
	Iterator Handle definition.
typedef spec::View	View
	Iterator View definition.
typedef spec::Holder	Holder
	Iterator Holder definition.
Public Member Functions
virtual bool	hasNext () const =0
	Determine if the iteration has another element.
virtual Object::Holder	next ()=0
	Return the next element in the iterated series.

virtual bool hasNext ( ) const [pure virtual]

Determine if the iteration has another element.

virtual Object::Holder next ( ) [pure virtual]

Return the next element in the iterated series.

Exceptions:

coherence::lang::NoSuchElementException

if iteration has no more elements
