 You can see that the Node A is still part of the main graph. It is XL query-able and reachable from B by following the edge EDGE_O. However, as the Node A is not connected to the Root by neither BRANCH, nor SUCCESSOR edge, it will not be displayed (not part of the 3d view, and raytracer). You can see that the Node A is still part of the main graph.

 +**Note:** In the example we used EDGE_O, there are actually 13 usable unique bit-wise edge type defined in Library: EDGE_0 to EDGE_12. But it is also possible to use any Integer as "unique" edge bit. It is still important to know that the edge bit is used for bit wise operations. Thus if the edge bit you use contains the bit SUCCESSOR, the edge will be a successor.

 +==== Example code ====
 +
 +<code java>
 +module A;
 +static int e = Library.EDGE_0;
 +module B {
 + public A* getA(){
 + yield (* @128; this -e-> A*);
 + }
 +}

 +protected void init ()

 + Axiom ==> A F ;

 + 
 +public void grow()[
 + a:A ==>  B [-e->a], a.setExtentIndex(7);
 +]
 +
 +public void printParent()[
 + b:B ::> println(b.getA());
