CGAL 5.1.2 - dD Range and Segment Trees
|
Defines the requirements that a Sublayer_type
of class CGAL::Range_tree_d
or CGAL::Segment_tree_d
has to fulfill.
First of all, the class has to be derived from the abstract base class CGAL::Tree_base
and therefore has to provide methods make_tree
, window_query
, enclosing_query
and is_inside
with the same parameter types as the instantiated class Range_tree_d
or Segment_tree_d
, respectively. Furthermore a method bool is_anchor()
has to be provided. If the Sublayer_type
class builds a recursion anchor for class Segment_tree_d
, this function is expected to return true
, false
otherwise.
Such a recursion anchor class is provided by the class class. CGAL::Tree_anchor<Data, Window>
.
