Method Detail

getSpeed

protected double getSpeed(ReaderWay way)

getAccess

public WayAccess getAccess(ReaderWay way)

Description copied from class: VehicleTagParser

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 VehicleTagParser

Returns:

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

handleWayTags

public IntsRef handleWayTags(IntsRef edgeFlags,
                             ReaderWay way)

Description copied from class: VehicleTagParser

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

Specified by:

handleWayTags in class VehicleTagParser

applyMaxSpeed

protected double applyMaxSpeed(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.

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
