set_to_begin incorrect for graph iterator #47

Closed monora closed 5 years ago

monora commented 5 years ago

The following test currently fails for bfs_iterator:

def test_bfs_stream_protocol
    it = @dg.bfs_iterator(1)
    assert_true(it.at_beginning?)

    it.set_to_end()
    assert_true(it.at_end?)

    it.set_to_begin()
    # Initial state is not correctly set. Therefor this check fails:
    assert_true(it.at_beginning?)
end
