[Biojava-l] order of circular and compound location

[Schreiber, Mark]

Hi -
 
I'm not sure I follow why you want to have any particular location first. The locations are by nature circular so the location you want is simply a circular permutation of the one reported so unless I'm mistaken they are the same thing aren't they?

	Hi,
	
	I am using CircularLocation and LocationTools.union(Location a, Location b).
	I would like to build a compound location including CircularLocation
	but the order of sublocation seems to miss in this case.
	
	The details are as folllows.
	
	A sample program
	---
	import org.biojava.bio.symbol.*;
	import java.util.*;
	
	public class CircularTest2 {
	        public static void main(String[] args) throws Exception {
	                CircularLocation[] locs = new CircularLocation[3];
	                locs[0] = LocationTools.makeCircularLocation(13,14,20);
	                locs[1] = LocationTools.makeCircularLocation(18,4,20);
	                locs[2] = (CircularLocation)LocationTools.union(locs[0], locs[1]
	);
	                System.out.println(locs[2].toString());
	                for(Iterator it = locs[2].blockIterator(); it.hasNext();) {
	                        System.out.println(((Location)it.next()).toString());
	                }
	        }
	}
	---
	
	Result
	---
	1, 20 {([1,4]), ([13,14]), ([18,20])}  (circular)
	[1,4]
	[13,14]
	[18,20]
	---
	
	I would like to get a sublocation [13,14] at first.
	How do I get a correct order in this case?
	Does anyone have any suggestion?
	
	Regards,
	Yasumasa Shigemoto
