I (I)

Definition

A class I that satisfies the requirements of an interface class for a KD-tree class must provide the following types and operations.

Types

I::Point
A type to hold a input item.

Operations

static CGAL_Comparison_result
i.compare ( int k, Point p0, Point p1)
compare the k-th coordinate of $p0$ and $p1$ . Return CGAL_LARGER if $p0$ _k > p1_k, CGAL_SMALLER if $p0$ _k < p1_k, or else CGAL_EQUAL.

static void i.copy_coord ( int k, Point & dest, Point src)
Copy the $k$ -th coordinate of $src$ to the $k$ -th coordinate of $dest$ .

static int i.dimension ( Point pnt)
return the dimension of pnt
