```
public final class SelectableRange
extends java.lang.Object
```
An object that represents a range of values to select from a list. A range has a start value, an end value, and whether we should pick inclusive or exclusive of the end value. The start value may be a concrete value from the set or it may be a flag that represents the start or end of the list.
For example, to select the first item from a set the range would be;
```
 RANGE:
   start = FIRST_VALUE, first
   end   = LAST_VALUE, first
 
```
To select the last item from a set the range would be;
```
 RANGE:
   start = FIRST_VALUE, last
   end   = LAST_VALUE, last
 
```
To select the range of values between '10' and '15' then range would be;
```
 RANGE:
   start = FIRST_VALUE, '10'
   end   = LAST_VALUE, '15'
 
```
Note that the the start value may not compare less than the end value. For example, start can not be 'last' and end can not be 'first'.
