Uncooked Spaghetti and its connected partners

G

Morning All, I have 4 lines, (A,B,C,D) all connected together in a straight line (like a piece of uncooked spaghetti). Its trivial to establish that A is connected to B, B to C and C to D. How do i establish that A is connected to C and D ? i have tried using the network topology tools to work out that all the segments are on the same network graph but ran out of ideas ( this isn't my preferred approach anyway). Are there any others ways/suggestions/techniques is should think about. Can FME iterate thru objects? ie spatial relate A to B, then B to C then pass this info back to A ? Many Thanks for your suggestions /input

You can use the LineJoiner to merge the connected lines. If you use the list option you will get a list of attributes from all the merged lines. That list will contain 4 entries in this case (A, B, C and D). This list can be used to check if lines are connected (via other lines) as the are in the same list.
