[geos-devel] Object Destruction

My comment just pointed out a de-facto situation:
JTS had no destructors.

In trunk we finally prevented GeometryFactory destruction via delete,
delegating it instead to its .destroy() method.

But I think you're asking about Geometry and CoordinateSequence ?

As mentioned 4 years ago, if you feel something is needed there,
please send a patch. The maintained API for GEOS is the C-API which
should have destruction methods for all objects.
