I'm unable to run any of the Jung examples that set or change the Vertex (or other Transformers). I receive the following error:

The method setVertexFillPaintTransformer(Function) in the type RenderContext is not applicable for the arguments (Transformer<String,Paint>)

The sample code:

        vv.getRenderContext().setVertexFillPaintTransformer(vertexPaint);

where vertexPaint is 

Transformer<String,Paint> vertexPaint = new Transformer<String,Paint>() {
           public Paint transform(String b) {
              return Color.orange;
           }
        };

It looks like you're using version 2.1.* of the JUNG libraries (which uses the Guava types in place of the old common-collections-generics types such as Transformer: https://github.com/jrtom/jung/releases), but using an older version of the sample code.

If you use the version of the sample code that comes with 2.1.1, you should be fine.

  • I've found the samples and pulled down the latest git, but I'm unable to compile them - the most basic issue is that it seems to be getting confused - a typical error is "The constructor VisualizationViewer(Network, LayoutAlgorithm, Dimension) is undefined" - it looks like the code isn't using the right Jung version, even though I'm bringing in only Jung 2.1.1 libraries – anarche Mar 28 '18 at 04:10
  • I should mention that I'm adding the guava maven dependency, else it complains - com.google.guava guava 24.1-jre – anarche Mar 28 '18 at 04:13
