Detailed Description

template<typename TValue, unsigned int N, unsigned int M>
class DGtal::IndexedListWithBlocks< TValue, N, M >::ConstIterator

Pseudo-random iterator to visit IndexedListWithBlocks (it is only a random forward iterator). Model of boost::ForwardIterator. Provides also + and += arithmetic.

Member Function Documentation

◆ operator!=()

template<typename TValue , unsigned int N, unsigned int M>
bool DGtal::IndexedListWithBlocks< TValue, N, M >::ConstIterator::operator!= ( const Self &  other) const

Inequality operator.

Parameters
otherany other iterator.
Returns
'true' iff the iterators points on different elements.

Reference DGtal::IndexedListWithBlocks< TValue, N, M >::ConstIterator::operator* ( ) const

Dereference operator.

Returns
the current value of the iterator, if valid.
