template<class It >

int GrAL::iterator_range_size

(

It

it

)

[inline]

Compute the range of a GrAL-iterator.

Template parameters:

• It has It::IsDone()

This function is useful if the iterating over the possible values until no more values are there is the only way of determining the size of the sequence (this is true in particular for implicitly defined sequences)

Todo:

We could use iterator_traits<It>::difference_type for the result.
