Method Detail

initialize

public void initialize(Graph graph,
                       java.lang.String nodeType,
                       int attributeIndex,
                       double attributeValue,
                       int maxEdges)

Description copied from interface: EdgeCreator

Initialize this creator. This can only be done once

Specified by:

initialize in interface EdgeCreator

Overrides:

initialize in class EdgeCreatorImp

Parameters:

graph - The graph over which to create edges

nodeType - Which nodetype is the node to create edges over

attributeIndex - The attribute index over which to generate edges (ignored for creators that cannot handle attributes)

attributeValue - The attribute value over which to generate edges (ignored for creators that cannot handle values; otherwise ignored if value is Double.NaN)

maxEdges - The maximum number of outgoing edges to create from any given node

getName

public java.lang.String getName()

Description copied from interface: EdgeCreator

The name of this edge-creator

Specified by:

getName in interface EdgeCreator

Overrides:

getName in class BaseNumericEdgeCreator

getValue

protected double getValue(Node n)

Overrides:

getValue in class BaseNumericEdgeCreator

getWeightFast

protected double getWeightFast(Node src,
                               Node dest)

Overrides:

getWeightFast in class BaseNumericEdgeCreator

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

Specified by:

getWeight in interface EdgeCreator

Overrides:

getWeight in class BaseNumericEdgeCreator

Parameters:

src - The source node

dest - The destination node

Returns:

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