Class VehicleTagParser

java.lang.Object

com.graphhopper.routing.util.VehicleTagParser

All Implemented Interfaces:

TagParser

Direct Known Subclasses:

BikeCommonTagParser, CarTagParser, FootTagParser, RoadsTagParser

public abstract class VehicleTagParser
extends Object
implements TagParser

Abstract class which handles flag decoding and encoding. Every encoder should be registered to a EncodingManager to be usable.

Method Detail

init

public void init(DateRangeParser dateRangeParser)

setConditionalTagInspector

protected void setConditionalTagInspector(ConditionalTagInspector inspector)

isBlockFords

public boolean isBlockFords()

blockFords

protected void blockFords(boolean blockFords)

blockPrivate

protected void blockPrivate(boolean blockPrivate)

getConditionalTagInspector

public ConditionalTagInspector getConditionalTagInspector()

handleWayTags

public IntsRef handleWayTags(IntsRef edgeFlags,
                             ReaderWay way,
                             IntsRef relationFlags)

Specified by:

handleWayTags in interface TagParser

handleWayTags

protected abstract IntsRef handleWayTags(IntsRef edgeFlags,
                                         ReaderWay way)

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

handleNodeTags

public IntsRef handleNodeTags(IntsRef edgeFlags,
                              Map<String,Object> nodeTags)

Updates the given edge flags based on node tags

getAccess

public abstract WayAccess getAccess(ReaderWay way)

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

Returns:

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

isBarrier

public boolean isBarrier(ReaderNode node)

Returns:

true if the given OSM node blocks access for this vehicle, false otherwise

getMaxSpeed

public double getMaxSpeed()

getMaxSpeed

protected static double getMaxSpeed(ReaderWay way)

Returns:

Double.NaN if no maxspeed found

isValidSpeed

protected static boolean isValidSpeed(double speed)

Returns:

true if the given speed is not Double.NaN

getAverageSpeedEnc

public final DecimalEncodedValue getAverageSpeedEnc()

getAccessEnc

public final BooleanEncodedValue getAccessEnc()

setSpeed

protected void setSpeed(boolean reverse,
                        IntsRef edgeFlags,
                        double speed)

supportsTurnCosts

public boolean supportsTurnCosts()

getTurnCostEnc

public DecimalEncodedValue getTurnCostEnc()

getRestrictions

public final List<String> getRestrictions()

getName

public final String getName()

toString

public String toString()

Overrides:

toString in class Object
