CGAL::Periodic_3_triangulation_3::Iterator_type

The enum Periodic_3_triangulation_3::Iterator_type is defined by Periodic_3_triangulation_3 to specify the behavior of geometric iterators.

enum Iterator_type { STORED=0, UNIQUE, STORED_COVER_DOMAIN, UNIQUE_COVER_DOMAIN};

The elements of the enum have the following meaning:

STORED: Return all geometric primitives as they are stored internally in Triangulation_data_structure_3.
UNIQUE: Return only one representative of each geometric primitive even if the triangulation is computed in a multiply sheeted covering space. Choose the representative whose maximum offset is minimal but non-negative in each direction of space.
STORED_COVER_DOMAIN: Same as STORED but return additionally all primitives whose intersection with the original domain of the current covering space is non-empty.
UNIQUE_COVER_DOMAIN: Same as UNIQUE but return additionally all primitives whose intersection with the original domain is non-empty.
