python-scripting-plugin: get the avg. path length of the graph

Dear gephi developers, first of all, thanks for making this python scripting console.
My goal: I am trying to get the characteristic path length of the graph.

This feature required building the toolkit java libraries from the source.
Then, I added the libs.jar to the sys.path.
then, with the following scheme I could access their underlying classes

> > > from org.gephi.project.api import ProjectController

The problem is that, in order to get to my goal (execute the statistic graphDistance)
two inputs are required: 1) GraphModel or HierarchicalGraph 2) attributeModel

1)A valid first input can be obtained through

> > > gu =g.getUnderlyingGraph()
> > > gu is a subclass of HierarchicalGraph, so it's ok
> > > gu.class.**bases**[0].**bases**[0]
> > > < type 'org.gephi.graph.api.HierarchicalGraph'>

2) The second input seems to be more problematic.
it should be of type: org.gephi.data.attributes.api.AttributeModel
How do I get to this?

here is what I tried:

> > > GraphController.getModel() #getGraphModel()
> > > AttributeController.getModel() #getAttributeModel()
> > > AttributeController.getModel().getDirectedGraph()
> > > AttributeController.getModel().getDirectedGraph().getGraph()

All of these complain that no argument is given:
File "", line 1, in
TypeError: getModel(): expected 1-2 args; got 0

Their autocompletion suggest that either giving no arg shoud be ok (but it doesn't work) either arg should be Workspace.
I can't get even get the workspace, for the same reason:

> > > ProjectController.closeCurrentProject()
> > > ProjectController.newProject();
> > > ProjectController.getCurrentWorkspace()
> > > ProjectController.getCurrentProject().

Strange enough, all of these should require no arguments, but my command line replies the same error:
File "", line 1, in
TypeError: getModel(): expected 1-2 args; got 0

Do you guys have a suggestion how to obtain the attributemodel, or even better how to reach directly the average path length?
