Method Detail

getName

public java.lang.String getName()

Description copied from interface: EdgeCreator

The name of this edge-creator

canHandle

public boolean canHandle(Attribute attribute)

Description copied from interface: EdgeCreator

Queries the edge creator if it can handle (i.e., create edges for) the given attribute.

Returns:

true if this edge creator can create edges based on the given Attribute

getWeight

public double getWeight(Node src,
                        Node dest)

Description copied from interface: EdgeCreator

Calculate the edgeweight from node src to node dest. Assumes that initialize has already been called, so that the creator knows the graph, the class attribute index and the attribute index

Parameters:

src - The source node

dest - The destination node

Returns:

the weight of the edge, Double.NaN if no edge should be created.

buildModel

public void buildModel(DataSplit split)

Description copied from interface: EdgeCreator

Build a model of edge creation based on the data split. Must be called before calling any analytic methods.

Specified by:

buildModel in interface EdgeCreator

Overrides:

buildModel in class EdgeCreatorImp
