Basics
The following examples use Extent2. Here we construct an empty Extent2.
Extent2 ext = new Extent2( );
This is construction from two Extent objects. The result is an Extent2 that contains two
separate Extent objects. In the case of an Extent3, the input would be three separate
Extent objects and the result would be an Exent3.
Extent x = new Extent (5, 10);
Extent y = new Extent (25, 15);
Extent2 ext2 = new Extent2 (x, y);
Here we construct a copy of an Extent2.
Extent2 copyExt2 = new Extent2 (ext2);
This is construction from an Extent[ ] array. The quantity of Extent objects in the
input array that ends up in the created Extent2 or Extent3 is either two or three
respectively. For example, using an array of three Extent objects to create an Extent2
will create an Extent2 that only contains the first two members of the array.
public Extent2 (Extent[ ] rhs);
This one constructs from two Index2 objects. The first Index2 object values define the
beginning values for each Extent in the Extent2. The second Index2 object values
define the size of each Extent in the Extent2 object. Using the Index2 of (5, 10) for
the beginning value and (20, 50) for the sizes, we end up with an Extent2 that contains
two Extent objects whose values range from 5 to 24 and 10 to 59 respectively.
// Starts for Extents of 5 and 10
Index2 begin = new Index2 (5, 10);
// Size of each extent as 20 for first, 50 for second
Index2 size = new Index2(20, 50);
Extent2 ext2 = new Extent2(begin, size);
// Result [5 : 1 : 24, 10 : 1 : 59]
Here we construct from three Index2 objects. The first are the beginning values. The
second are the size values. The third Index2 are the increments between values. Using
