Constructor Detail

CarFlagEncoder

public CarFlagEncoder()

CarFlagEncoder

public CarFlagEncoder(PMap properties)

CarFlagEncoder

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

Method Detail

setSpeedTwoDirections

public CarFlagEncoder setSpeedTwoDirections(boolean value)

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)

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

Overrides:

createEncodedValues in class AbstractFlagEncoder

getSpeed

protected double getSpeed(ReaderWay way)

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.

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.

Specified by:

handleWayTags in class AbstractFlagEncoder

isBackwardOneway

protected boolean isBackwardOneway(ReaderWay way)

make sure that isOneway is called before

isForwardOneway

protected boolean isForwardOneway(ReaderWay way)

make sure that isOneway is called before

isOneway

protected boolean isOneway(ReaderWay way)

applyBadSurfaceSpeed

protected double applyBadSurfaceSpeed(ReaderWay way,
                                      double speed)

Parameters:

way - needed to retrieve tags

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

Returns:

The assumed speed

toString

public String toString()

Overrides:

toString in class Object
