bxt / daglayout Goto Github PK

Hi Rodrego, 
What methods does one need to override and implement in a class in order to
use it as a Vertex in DAGLayout?

I have overrides for equals and hashCode and implement compareTo.
But still the compiler gives me 'type parameter X is is not within its
bound' with a decleration like 
DAGLayout<X,String> layout= new DAGLayout<X,String>();

What am I missing?
using Java 1.6 

    protected void assignLayers(Virtualizable<V> v, Layer<V> layer) {

        int previousLayerOfNode;
        int thisLevel = layer.getLevel();
        layer.add(v);
        this.vertexLevel.put(v, thisLevel);

        for (Virtualizable<V> child : this.virtualGraph.getSuccessors(v)) {
            if (this.vertexLevel.containsKey(child)) {
                previousLayerOfNode = this.vertexLevel.get(child);
                if (thisLevel >= previousLayerOfNode) {
                    layer.getLayerOnLevel(previousLayerOfNode).remove(child);
                    this.vertexLevel.remove(child);
                    // When calling assignLayers again, all the descendants of
                    // this node will be reassigned
                    // FIXME: This algorithm is not efficient at all!
                } else {
                    /*
                     * We stop the iteration if the child is already in a level
                     * bigger than this one
                     */
                  //return;  <- Wrong
                    continue;
                }
            }
            assignLayers(child, layer.getNextLayer(true));
        }
    }
