grid_key_dx_iterator_sub< 0, warn > Class Template Reference

Detailed Description

template<typename warn>
class grid_key_dx_iterator_sub< 0, warn >

Grid key class iterator, iterate through a sub-grid defined by an hyper-cube

Parameters

dim	dimensionality of the grid

Note

if you have a grid you can get this object from getIteratorSub()

Sub grid iterator declaration and usage

    // Subdivisions
    size_t div[3] = {16,16,16};

    // grid info
    grid_sm<3,void> g_info(div);

    grid_key_dx<3> start(1,1,1);
    grid_key_dx<3> stop(14,14,14);

    // Create a grid iterator (start and stop included)
    grid_key_dx_iterator_sub<3> g_it(g_info,start,stop);

    // Iterate on all the elements
    while (g_it.isNext())
    {
        grid_key_dx<3> key = g_it.get();

        // set the grid key to zero without any reason ( to avoid warning compilations )
        key.zero();

        count++;

        ++g_it;
    }

    BOOST_REQUIRE_EQUAL(count, (size_t)14*14*14);
