Class Coordinate

java.lang.Object

de.tsl2.nano.math.vector.Coordinate

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

Point, Rectangle, Vector

public class Coordinate
extends Object
implements Serializable

Basic simple handling n-dim coordinate. the coordinates are floats, as they will fulfill most cases.

It is not possible to use java generics, because no primitives are possible. If you use the wrappers of type Number, you are not able to do math calculations.

 Example:
  public class Coordinate {
  ...
     public void add(T... v) {
         checkDimension(v);
         for (int i = 0; i < v.length; i++) {
         // this is not possible, as the generic type T cannot use autoboxing
             x[i] = x[i] + v[i];
         }
     }
     ...
     }
