Detailed Description

template<typename TRange, typename TFunctor, typename TReturnType>
class DGtal::ConstRangeFromPointAdapter< TRange, TFunctor, TReturnType >

Aim: model of CConstBidirectionalRangeFromPoint that adapts any bidirectional range and provides services to iterate over it (in a read-only manner).

Template Parameters

TRange a model of CConstBidirectionalRangeFromPoint

Moreover, the provided iterators are adapted with a functor f given at construction so that operator* calls f(*it), instead of calling directly operator* of the iterator it.

Template Parameters

TFunctor	the type of functor that transforms the pointed element into another one
TReturnType	the type of the element returned by the underlying functor.

NB: the underlying range and functor are stored as aliasing pointers in order to avoid copies. As a consequence the pointed object must exist and must not be deleted during the use of any instance of this class.
