                              int maxTurnCosts)

Method Detail

getVersion

public int getVersion()

Specified by:

getVersion in interface FlagEncoder

Overrides:

getVersion in class BikeFlagEncoder

Returns:

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

defineWayBits

public int defineWayBits(int index,
                         int shift)

Description copied from class: AbstractFlagEncoder

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

Overrides:

defineWayBits in class BikeCommonFlagEncoder

shift - bit offset for the first bit used by this encoder

Returns:

incremented shift value pointing behind the last used bit

getReverseSpeed

public double getReverseSpeed(long flags)

Specified by:

getReverseSpeed in interface FlagEncoder

Overrides:

getReverseSpeed in class AbstractFlagEncoder

Returns:

the speed of the reverse direction in km/h

setReverseSpeed

public long setReverseSpeed(long flags,
                            double speed)

Description copied from interface: FlagEncoder

Sets the reverse speed in the flags.

Specified by:

setReverseSpeed in interface FlagEncoder

Overrides:

setReverseSpeed in class AbstractFlagEncoder

handleSpeed

public long handleSpeed(ReaderWay way,
                        double speed,
                        long flags)

Overrides:

handleSpeed in class BikeCommonFlagEncoder

setLowSpeed

protected long setLowSpeed(long flags,
                           double speed,
                           boolean reverse)

Overrides:

setLowSpeed in class AbstractFlagEncoder

flagsDefault

public long flagsDefault(boolean forward,
                         boolean backward)

Description copied from class: AbstractFlagEncoder

Sets default flags with specified access.

Overrides:

flagsDefault in class AbstractFlagEncoder

setProperties

public long setProperties(double speed,
                          boolean forward,
                          boolean backward)

Description copied from interface: FlagEncoder

Sets speed and access properties.

Specified by:

setProperties in interface FlagEncoder

Overrides:

setProperties in class AbstractFlagEncoder

Returns:

created flags

reverseFlags

public long reverseFlags(long flags)

Description copied from class: AbstractFlagEncoder

Swapping directions means swapping bits which are dependent on the direction of an edge like the access bits. But also direction dependent speed values should be swapped too. Keep in mind that this method is performance critical!

Overrides:

reverseFlags in class AbstractFlagEncoder

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

toString

public String toString()

Overrides:

toString in class BikeFlagEncoder
