Re: Issues accessing class attributes of external package distance function

Hello Michael,

 

my described approach using the getMatricesDilca method works, but doing that or subclassing from java would still mean I would have to instruct the user, aiming at reproducing my research, to build a new jar and overwrite the existing one, right? I want to avoid this specifically and enable the user to use official-package-extended Weka (without having to use java-related build tools). 

 

Best

Martin

From java make a subclass with

 

public Vector<double[][]> matricesDilca;

 

Maybe call it something like AccessibleDilcaDistance

 

I’ve done similar with Weka before

 

Although I’m not exactly following your objections to the public Object[] getMatricesDilca() method.

I think you could in your subclass change that to return the actual Vector<double[][]> type if that is the problem?

My understanding of Python isn’t good enough to know how you would do that from there.
