Defining an Extent with a starting value of 50 and containing 100 members incrementing
by 1 would be done by:
Extent myExt = new Extent(50, 100);
The range of values in this Extent would run from 50 to 149. The number of values may
not be negative.
Table 4-1 Extent Object Values Example
50 51 52 53 54 55 56 ... 148 149
To use an increment other than 1 the constructor for the Extent is changed. For an
increment of 2 the code would be:
Extent myExt = new Extent(50, 100, 2);
The range of values in this Extent would run from 50 to 248. The increment value may
be positive or negative but cannot be 0.
Table 4-2 Extent Object Values with Increment of 2
50 52 54 56 58 60 62 ... 246 248
Printing an Extent with the ToString method results in a notation of “begin : inc :
end”. So for the Extent created by “new Extent(50, 100, 2)” the ToString result
is “50 : 2 : 248”.
