Method Summary

Modifier and Type	Method and Description
void	applyWayTags(ReaderWay way, EdgeIteratorState edge) Second parsing step.
protected double	correctErrors(double bendiness) A really small bendiness or a bendiness greater than 1 indicates an error in the calculation.
void	createEncodedValues(List<EncodedValue> registerNewEncodedValue, String prefix, int index) Define the place of the speedBits in the edge flags for car.
protected double	discriminateSlowStreets(double bendiness, double speed) Streets that slow are not fun and probably in a town.
EncodingManager.Access	getAccess(ReaderWay way) Decide whether a way is routable for a given mode of travel.
int	getVersion()
IntsRef	handleWayTags(IntsRef edgeFlags, ReaderWay way, EncodingManager.Access accept) Analyze properties of a way and create the edge flags.
protected double	increaseBendinessImpact(double bendiness) A good bendiness should become a greater impact.
boolean	supports(Class<?> feature) Returns true if the feature class is supported like TurnWeighting or PriorityWeighting.

Constructor Detail

MotorcycleFlagEncoder

public MotorcycleFlagEncoder()

MotorcycleFlagEncoder

public MotorcycleFlagEncoder(PMap properties)

MotorcycleFlagEncoder

public MotorcycleFlagEncoder(int speedBits,
                             double speedFactor,
                             int maxTurnCosts)

Method Detail

getVersion

public int getVersion()

Specified by:

getVersion in interface FlagEncoder

Overrides:

getVersion in class CarFlagEncoder

Returns:

the version of this FlagEncoder to enforce none-compatibility when new attributes are introduced

createEncodedValues

public void createEncodedValues(List<EncodedValue> registerNewEncodedValue,
                                String prefix,
                                int index)

Define the place of the speedBits in the edge flags for car.

Overrides:

createEncodedValues in class CarFlagEncoder

getAccess

public EncodingManager.Access getAccess(ReaderWay way)

Description copied from class: AbstractFlagEncoder

Decide whether a way is routable for a given mode of travel. This skips some ways before handleWayTags is called.

Overrides:

getAccess in class CarFlagEncoder

Returns:

the encoded value to indicate if this encoder allows travel or not.

handleWayTags

public IntsRef handleWayTags(IntsRef edgeFlags,
                             ReaderWay way,
                             EncodingManager.Access accept)

Description copied from class: AbstractFlagEncoder

Analyze properties of a way and create the edge flags. This method is called in the second parsing step.

Overrides:

handleWayTags in class CarFlagEncoder

applyWayTags

public void applyWayTags(ReaderWay way,
                         EdgeIteratorState edge)

Description copied from class: AbstractFlagEncoder

Second parsing step. Invoked after splitting the edges. Currently used to offer a hook to calculate precise speed values based on elevation data stored in the specified edge.

Overrides:

applyWayTags in class AbstractFlagEncoder

discriminateSlowStreets

protected double discriminateSlowStreets(double bendiness,
                                         double speed)

Streets that slow are not fun and probably in a town.

correctErrors

protected double correctErrors(double bendiness)

A really small bendiness or a bendiness greater than 1 indicates an error in the calculation. Just ignore them. We use bendiness greater 1.2 since the beelineDistance is only approximated, therefore it can happen on straight roads, that the beeline is longer than the road.

increaseBendinessImpact

protected double increaseBendinessImpact(double bendiness)

A good bendiness should become a greater impact. A bendiness close to 1 should not be changed.

supports

public boolean supports(Class<?> feature)

Description copied from interface: FlagEncoder

Returns true if the feature class is supported like TurnWeighting or PriorityWeighting. Use support(String) instead.

Specified by:

supports in interface FlagEncoder

Overrides:

supports in class AbstractFlagEncoder

toString

public String toString()

Overrides:

toString in class CarFlagEncoder
