Class CachedPointSet

java.lang.Object
  extended by umontreal.iro.lecuyer.hups.PointSet
      extended by umontreal.iro.lecuyer.hups.CachedPointSet

public class CachedPointSet
extends PointSet

This container class caches a point set by precomputing and storing its points locally in an array. This can be used to speed up computations when using a small low-dimensional point set more than once.


Constructor Summary
CachedPointSet(PointSet P)
          Creates a new PointSet object that contains an array storing the points of P.
CachedPointSet(PointSet P, int n, int dim)
          Creates a new PointSet object that contains an array storing the first dim coordinates of the first n points of P.
 
Method Summary
 double getCoordinate(int i, int j)
          Returns ui, j, the coordinate j of the point i.
 String toString()
          Formats a string that contains the information about the point set.

Constructor Detail

CachedPointSet

public CachedPointSet(PointSet P,
                      int n,
                      int dim)
Creates a new PointSet object that contains an array storing the first dim coordinates of the first n points of P. The original point set P itself is not modified.

Parameters:
P - point set to be cached
n - number of points
dim - number of dimensions of the points

CachedPointSet

public CachedPointSet(PointSet P)
Creates a new PointSet object that contains an array storing the points of P. The number of points and their dimension are the same as in the original point set. Both must be finite.

Parameters:
P - point set to be cached
Method Detail

toString

public String toString()
Description copied from class: PointSet
Formats a string that contains the information about the point set.

Overrides:
toString in class PointSet
Returns:
string representation of the point set information

getCoordinate

public double getCoordinate(int i,
                            int j)
Description copied from class: PointSet
Returns ui, j, the coordinate j of the point i.

Specified by:
getCoordinate in class PointSet
Parameters:
i - index of the point to look for
j - index of the coordinate to look for
Returns:
the value of ui, j
