[OpenLayers-Users] check line intersection while polygon editing

[G. Allegri]

Is there in the API a ready-to-use function to check if lines
intersect while editing a polygonal geometry? I was thinking to
something like the isSimple function of GEOS (also used by PostGIS),
but that would raise a callback if one line touches another (given a
certain tolerance) while editing, not at the end.
