Detailed Description

template<typename left_base_iterator_type_, typename right_base_iterator_type_, typename func_type_, bool is_static_ = true>
class lite::b_iterator< left_base_iterator_type_, right_base_iterator_type_, func_type_, is_static_ >

This class implements an iterator that returns the result of applying a binary function object to the return value of two other iterators.

The type left_base_iter_type_ and right_base_iter_type_ specify the type of the underlying iterators. The type func_type_ specifies the type of the binary function object that is applied to the return value of the the two bsae iterators. If is_static_ is true then the function object will be a static member of the b_iterator object and thus won't occupy any memory in the b_iterator object. If is_static_ is false then the function object will be a regular member of the b_iterator object and thus will occupy memory in the b_iterator object.

All the required operations (i.e. at(), inc(), dec(), shift()) are also defined.

Example:

        typedef array<float[2][2]> A;

        A a1, a2;

        typedef b_iterator<A::iterator, A::iterator, lite::plus, true> Iter; 
        typedef array<float[2][2], default_array_traits, reference_rep<Iter> > B;

        B b(Iter(a1.begin(), a2.begin()), a1.size());

        std::cin >> a1 >> a2; 
        std::cout << b << std::endl;

Assuming that the input is:

        1 2
        3 4
        1 10
        10 1
    

The output would be:

        2 12
        13 5

template<typename left_base_iterator_type_, typename right_base_iterator_type_, typename func_type_, bool is_static_ = true>

template<typename other_left_base_iterator_type_ , typename other_right_base_iterator_type_ >

LITE_INLINE lite::b_iterator< left_base_iterator_type_, right_base_iterator_type_, func_type_, is_static_ >::b_iterator

(

const b_iterator< other_left_base_iterator_type_, other_right_base_iterator_type_, func_type_, is_static_ > &

other

)

[inline]

Creates a b_iterator with the base iterators lbase_iter and rbase_iter and the function object func.

Remarks:

This constructor is defined only if is_static_ is false.
