Basics
CreateIncreasing - This method creates Extent and reverts values to ensure new
extent has positive increment. This method is static.
Extent increasingExt = Extent.CreateIncreasing(20, 10, -2);
// result is 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
Reverse - This method creates a reversed copy of the object.
Extent myExt = new Extent(5, 10);
Extent reverseExt = myExt.Reverse();
// result is 14, 13, 12, 11, 10, 9, 8, 7, 6, 5
Accessing data in an Extent is done with a foreach loop.
Extent myExt = new Extent(5, 10);
foreach (int val in myExt)
{
// val will be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
...
}
Extent2 and Extent3 Classes
Extent2 and Extent3 are also sealed classes that derive from ExtendKdBase class.
They both provide pretty much the same constructors, properties, and methods as the
Extent class.
