Segments
segment object and related functions.
Segments are defined by their two #GtsVertex. They are not oriented.
When destroying a #GtsSegment, all the vertices not used by another edge are also destroyed. This default behaviour can be changed punctually by setting the global variable gts_allow_floating_vertices to %TRUE. You must not forget to set this variable back to %FALSE as all the algorithms of GTS assume the default behaviour.
Casts @klass to #GtsSegmentClass.
@klass: a descendant of #GtsSegmentClass.
Casts @obj to #GtsSegment.
@obj: a descendant of #GtsSegment.
Evaluates to %TRUE if @obj is a descendant of #GtsSegment, %FALSE otherwise.
@obj: a pointer to test.
The segment class. No virtual functions are assiocated.
@parent_class:
The segment object.
@object: The parent object.
@v1: First endpoint of the segment.
@v2: Second endpoint of the segment.
