public class TLcdCompositeEdgeValueFunction<N,E> extends java.lang.Object implements ILcdEdgeValueFunction<N,E>
TLcdCompositeEdgeValueFunctionprovides an implementation of
ILcdEdgeValueFunctionwhich can be used to compose a complex edge value function out of two or more simple edge value functions.

public TLcdCompositeEdgeValueFunction(ILcdEdgeValueFunction<N,E> aEdgeValueFunctions)
TLcdCompositeEdgeValueFunctionwith the given array of
aEdgeValueFunctions- the edge functions from which this edge function is composed.
java.lang.NullPointerException- if the array is
public double computeEdgeValue(ILcdGraph<N,E> aGraph, ILcdRoute<N,E> aPrecedingRoute, E aEdge, TLcdTraversalDirection aTraversalDirection)
aGraph- the graph from which the edge is part.
aPrecedingRoute- the route, to which the edge connects (i.e. the end node of this route is one of the two nodes connected by the edge). Depending on the function, the information used from this route in the calculation of the edge value can differ: a simple distance function will not use any information from this route, while a turn function which describes a relationship between two succeeding edges will typically use the last edge of the route in its calculation. The route should be completely contained in the given graph, otherwise the correct behavior of this method is not guaranteed.
aEdge- the edge for which a value should be returned. This edge should be part of the given graph and adjacent to the end of the given route, otherwise the correct behavior of this method is not guaranteed.
