creating a chain using the java Vector class
Jan 14th, 2008, 12:40pm  
Hello all!

I wrote a test sketch that will be used with the reacTIVision server and implemented in the P5 client demo.

The idea is to link objects when they are within a certain range.
There are two kind of objects :
-parameterMarkers (these object change the apperance of prototypeMarkers)
-prototypeMarkers (these objects will be transformed if one or several parameterMarkers is close enough)

I want to use the java Vector class to create an expandable list of all linked objects.

Now I don't know how to do that. Here is what I want to do explained in a drawing : http://www.amorphik.com/mid/TUI/TUI_interface_links_explanation.png

and here is the code I've written so far :

Hi, just for information, using Vector is not recommended since it is kind of deprecated. You should use an ArrayList or any other java.util.List implementation instead.

What you could do is storing pointers to the connected objects in the object itself :

Code:
class MyObject {
  MyObject[] connectedObjects;
}

and store all connected objects in an ArrayList, so you can easily check with java.util.List.contains() if an object is already connected or not.
