Constructor Detail

WheelchairFlagEncoder

public WheelchairFlagEncoder()

Should be only instantiated via EncodingManager

WheelchairFlagEncoder

public WheelchairFlagEncoder(PMap properties)

WheelchairFlagEncoder

protected WheelchairFlagEncoder(int speedBits,
                                double speedFactor)

Method Detail

getVersion

public int getVersion()

Specified by:

getVersion in interface FlagEncoder

Overrides:

getVersion in class FootFlagEncoder

Returns:

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

getAccess

public EncodingManager.Access getAccess(ReaderWay way)

Avoid some more ways than for pedestrian like hiking trails.

Overrides:

getAccess in class FootFlagEncoder

Returns:

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

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.

Overrides:

handleWayTags in class FootFlagEncoder

applyWayTags

public void applyWayTags(ReaderWay way,
                         EdgeIteratorState edge)

Calculate slopes from elevation data and set speed according to that. In-/declines between smallInclinePercent and maxInclinePercent will reduce speed to SLOW_SPEED. In-/declines above maxInclinePercent will result in zero speed.

Overrides:

applyWayTags in class AbstractFlagEncoder

handlePriority

protected int handlePriority(ReaderWay way,
                             Integer priorityFromRelation)

First get priority from FootFlagEncoder.handlePriority(ReaderWay, Integer) then evaluate wheelchair specific tags.

Returns:

a priority for the given way

toString

public String toString()

Overrides:

toString in class FootFlagEncoder
