Constructor Detail

ArrayPointSet

public ArrayPointSet(int d,
                     int n)

Creates an array-based point set to store n d-dimensional points.

Parameters:

d - the dimensions of the ambient space

n - the number of points

Method Detail

size

public int size()

Description copied from interface: PointSet

Number of points.

Specified by:

size in interface PointSet

Returns:

the number of points in the point set.

dimension

public int dimension()

Description copied from interface: PointSet

The dimension of the ambient space of the points.

Each point has dimension() many Euclidean coordinates.

Specified by:

dimension in interface PointSet

Returns:

the dimension of the ambient space

coord

public double coord(int i,
                    int j)

Description copied from interface: PointSet

The jth Euclidean coordinate of the ith point.

Specified by:

coord in interface PointSet

Parameters:

i - the number of the point, 0 ≤ i < size()

j - the dimension of the coordinate of interest, 0 ≤ j ≤ dimension()

Returns:

the jth Euclidean coordinate of the ith point

set

public void set(int i,
                int j,
                double v)

Sets the jth Euclidean coordinate of the ith point to the given value.

Parameters:

i - the number of the point, 0 ≤ i < size()

j - the dimension of the coordinate of interest, 0 ≤ j ≤ dimension()

v - the value to set as the jth Euclidean coordinate of the ith point

toString

public java.lang.String toString()

Overrides:
