Detailed Description

template<typename TYPE, typename TOCHECKFUNCTOR = CheckAllFunctor<TYPE>>
class tlp::UniqueIterator< TYPE, TOCHECKFUNCTOR >

UniqueIterator enables to remove duplicated elements in an iterator.

Parameters:
it the iterator in which we want to filter out duplicated elements
checkFuncor a functor that enable to indicate wheter or not the element could be duplicated (default test all elements)

The functor function shoul have the following form

 class ACheckFunctor {
  bool operator(TYPE a) {
   return true if a could be duplicated else false;
  }
 };

checkFunctor are used for optimization purpose to prevent to log(n) test for all elements when not necessary.

template<typename TYPE , typename TOCHECKFUNCTOR = CheckAllFunctor<TYPE>>
bool tlp::UniqueIterator< TYPE, TOCHECKFUNCTOR >::hasNext (  )  [inline, virtual]

Tells if the sequence is at its end.

Returns:
bool Whether there are more elements to iterate on.

Implements tlp::Iterator< TYPE >.
