## Definition

### template<class Traits, class VIM = Default, class HIM = Default, class FIM = Default, class VPM = Default>
class CGAL::Surface_mesh_shortest_path< Traits, VIM, HIM, FIM, VPM >::Source_point_iterator

A model of `BidirectionalIterator` to access the source points.

An iterator becomes invalid if:

- the corresponding point is removed (either with `Surface_mesh_shortest_path::remove_source_point()` or `Surface_mesh_shortest_path::remove_all_source_points()`).
- the structure is re-built (triggered by a shortest path query or a call to `Surface_mesh_shortest_path::build_sequence_tree()`).
- the structure is cleared (`Surface_mesh_shortest_path::clear()`).

Dereferencing this iterator yields a `const Surface_mesh_shortest_path::Face_location&`.

This iterator supports equality comparison operations.
