Hi,

I am trying to run a graph metric algorithm in the jython console. Unfortunately I cannot call the method 'execute' in a GraphDistance object.

This is the class of statistics object I need to use:

Code: Select all

>>> type(gd)
<type 'org.gephi.statistics.plugin.GraphDistance'>

The type of the graph class is this:

Code: Select all

>>> type(gu)
<type 'org.gephi.graph.dhns.graph.HierarchicalUndirectedGraphImpl'>

That is actually a subclass of HierarchicalGraph:

Code: Select all

>>> gu.class.__bases__[0].__bases__[0]
<type 'org.gephi.graph.api.HierarchicalGraph'>

I also have the 'attributes' object as requested:

Code: Select all

>>> type(ga)
<type 'org.gephi.data.attributes.AttributeRowImpl'>

But the execute states that the required type is not correct:

Code: Select all

>>> gd.execute(gu,ga)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
TypeError: execute(): 1st arg can't be coerced to org.gephi.graph.api.HierarchicalGraph, org.gephi.graph.api.GraphModel

This does not make much sense for me since the class of the graph object I am using is derived from the class that is required.

Any ideas?

Hi,
The first argument actually looks fine, but the second argument should be of type org.gephi.data.attributes.api.AttributeModel instead of org.gephi.data.attributes.AttributeRowImpl.

Thanks! Do you know how to get the AttributeModel? I am trying to experiment with many methods of the 'g' global variable, but i am not finding anything useful.
cheers,

Hi,
Try the following code:

Code: Select all

import org.openide.util.Lookup;
import org.gephi.data.attributes.api.AttributeController;
org.openide.util.Lookup.getDefault().lookup(org.gephi.data.attributes.api.AttributeController).getModel();

You can obtain many different controllers such as GraphController, AttributeController or DynamicController in Gephi through the Lookup mechanism.
