Interface Analyser

All Known Implementing Classes:

HighwayAnalyser

public interface Analyser

Provides special-cased knowledge about generalising segments by combining. Clients must provide implementations of this interface that are tuned to the specific situation in which the generalisation is to be applied (for example, multi-track rail lines or dual carriageways). This interface is primarily used during the analysis for parallelisms.

Method Summary

Modifier and Type	Method and Description
int	compare(double value, double bestValue)
double	distance(Segment s1, Segment s2) The geometric distance between two segments (DISTANZ).
double	evaluateLeft(Segment currentPart, Segment otherPart)
double	evaluateRight(Segment currentPart, Segment otherPart)
boolean	shouldEvaluate(Segment currentPart, Segment otherPart)
double	worstResult()

Method Detail

shouldEvaluate

boolean shouldEvaluate(Segment currentPart,
                       Segment otherPart)

distance

double distance(Segment s1,
                Segment s2)

The geometric distance between two segments (DISTANZ). How the distance is determined may depend upon the use case. For example, in one context the distance between two segments might be best defined as the distance of their mid points, whereas other contexts may require it to be defined as the average distance of their respective endpoints.

Returns:

an ordinal scaled value representing the distance between the two segments s1 and s2

Throws:

NullPointerException - if s1 or s2 are null

evaluateLeft

double evaluateLeft(Segment currentPart,
                    Segment otherPart)

evaluateRight

double evaluateRight(Segment currentPart,
                     Segment otherPart)

compare

int compare(double value,
            double bestValue)

worstResult

double worstResult()
