public class CachedPointSet
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. |
