How would one construct an NSIndexSet containing the indices 2,4,5 ?

I did:

	NSRange two = NSMakeRange(2, 1);
	NSRange four = NSMakeRange(4, 1);
	NSRange five = NSMakeRange(5, 1);
	NSRange u1 = NSUnionRange(two,four);
	NSRange u2 = NSUnionRange(u1,five);
	id indices = [NSIndexSet indexSetWithIndexesInRange:u2];
But, of course, NSUnionRange adds 3 so indices becomes 2,3,4,5.

Or, should one even use NSIndexSet?


Yes and no, It should use an NSMutableIndexSet.
