| 22 * Instances of this class represent places on the (x, y) | |
| 23 * coordinate plane. | |
| 24 * <p> | |
| 25 * The coordinate space for rectangles and points is considered | |
| 26 * to have increasing values downward and to the right from its | |
| 27 * origin making this the normal, computer graphics oriented notion | |
| 28 * of (x, y) coordinates rather than the strict mathematical one. | |
| 29 * </p> | |
| 30 * <p> | |
| 31 * The hashCode() method in this class uses the values of the public | |
| 32 * fields to compute the hash value. When storing instances of the | |
| 33 * class in hashed collections, do not modify these fields after the | |
| 34 * object has been inserted. | |
| 35 * </p> | |
| 36 * <p> | |
| 37 * Application code does <em>not</em> need to explicitly release the | |
| 38 * resources managed by each instance when those instances are no longer | |
| 39 * required, and thus no <code>dispose()</code> method is provided. | |
