Modifier	Constructor and Description

Method Summary

Modifier and Type	Method and Description
protected double	applyMaxSpeed(ReaderWay way, double speed) Apply maxspeed: In contrast to the implementation of the AbstractFlagEncoder, we assume that we can reach the maxspeed for bicycles in case that the road type speed is higher and not just only 90%.
void	createEncodedValues(List<EncodedValue> registerNewEncodedValue, String prefix, int index) Defines bits used for edge flags used for access, speed etc.
EncodingManager.Access	getAccess(ReaderWay way) Decide whether a way is routable for a given mode of travel.
TransportationMode	getTransportationMode()
int	getVersion()
protected void	handleSpeed(IntsRef edgeFlags, ReaderWay way, double speed)
IntsRef	handleWayTags(IntsRef edgeFlags, ReaderWay way, EncodingManager.Access access) Analyze properties of a way and create the edge flags.
boolean	supports(Class<?> feature) Returns true if the feature class is supported like TurnWeighting or PriorityWeighting.

Constructor Detail

BikeCommonFlagEncoder

protected BikeCommonFlagEncoder(int speedBits,
                                double speedFactor,
                                int maxTurnCosts)

Method Detail

getTransportationMode

public TransportationMode getTransportationMode()

getVersion

public int getVersion()

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)

Description copied from class: AbstractFlagEncoder

Defines bits used for edge flags used for access, speed etc.

Overrides:

createEncodedValues in class AbstractFlagEncoder

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.

Specified by:

getAccess in class AbstractFlagEncoder

Returns:

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

applyMaxSpeed

protected double applyMaxSpeed(ReaderWay way,
                               double speed)

Apply maxspeed: In contrast to the implementation of the AbstractFlagEncoder, we assume that we can reach the maxspeed for bicycles in case that the road type speed is higher and not just only 90%.

Overrides:

applyMaxSpeed in class AbstractFlagEncoder

Parameters:

way - needed to retrieve tags

speed - speed guessed e.g. from the road type or other tags

Returns:

The assumed average speed.

handleWayTags

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

Description copied from class: AbstractFlagEncoder

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

Specified by:

handleWayTags in class AbstractFlagEncoder

handleSpeed

protected void handleSpeed(IntsRef edgeFlags,
                           ReaderWay way,
                           double speed)

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
