The main algorithm Betweeness.java is based on Simple= ShortestPaths***.java. In order to implement the new algorithm I had to ove= rride the message value as well as the vertex value.

I dug up the examples, and the most compatible fi= les where the files about bracha-something calculation.

The overrided vertex value is myVertexValue.java and is based on =A0Bracha= *Value.java and in there lies the problem I suppose, probably due to miscon= figurating the serializer

// Serialization function=
s -----------------------------------------------


=
=A0=A0@Override
=A0=A0public void readFields(<=
/span>DataInput input<=
/span>) throws IOExceptio=
n {


=A0//   this.distance=3Di=
nput.readLong();
=A0	this.sigma=3Dinput.readDouble();


//	this.delta=3Dinput.rea=
dDouble();	
=A0=A0}



=A0=A0@Override
=A0=A0public void write(DataOutput output) throws IOException {
=A0=A0=A0=A0int sz;

<= span class=3D"" style>output.writeLong(this.= distance);
output.writeDouble(t= his.sigma);
output.writeDouble(t= his.delta);

=A0}


Of course, when I try to run the example I try to use the following handler= , that works for the simpleShortest paths, but now that I've overriden = the vertex value???

At the moment Iam in a stalemate.... Any ideas so that I can make eve= n a small step are needed... Thanks..
