Constructor Detail

EncodingManager

public EncodingManager(String flagEncodersStr)

Instantiate manager with the given list of encoders. The manager knows several default encoders ignoring case.

Parameters:

flagEncodersStr - comma delimited list of encoders. The order does not matter.

EncodingManager

public EncodingManager(String flagEncodersStr,
                       int bytesForEdgeFlags)

EncodingManager

public EncodingManager(FlagEncoderFactory factory,
                       String flagEncodersStr,
                       int bytesForEdgeFlags)

EncodingManager

public EncodingManager(FlagEncoder... flagEncoders)

Instantiate manager with the given list of encoders.

Parameters:

flagEncoders - comma delimited list of encoders. The order does not matter.

EncodingManager

public EncodingManager(List<? extends FlagEncoder> flagEncoders)

Instantiate manager with the given list of encoders.

Parameters:

flagEncoders - comma delimited list of encoders. The order does not matter.

EncodingManager

public EncodingManager(List<? extends FlagEncoder> flagEncoders,
                       int bytesForEdgeFlags)

Method Detail

create

public static EncodingManager create(FlagEncoderFactory factory,
                                     String ghLoc)

Create the EncodingManager from the provided GraphHopper location. Throws an IllegalStateException if it fails. Used if no EncodingManager specified on load.

getBytesForFlags

public int getBytesForFlags()

supports

public boolean supports(String encoder)

Returns:

true if the specified encoder is found

getEncoder

public FlagEncoder getEncoder(String name)

acceptWay

public long acceptWay(ReaderWay way)

Determine whether a way is routable for one of the added encoders.

handleRelationTags

public long handleRelationTags(ReaderRelation relation,
                               long oldRelationFlags)

handleWayTags

public long handleWayTags(ReaderWay way,
                          long includeWay,
                          long relationFlags)

Processes way properties of different kind to determine speed and direction. Properties are directly encoded in 8 bytes.

Parameters:

relationFlags - The preprocessed relation flags is used to influence the way properties.

Returns:

the encoded flags

toString

public String toString()

Overrides:

toString in class Object

toDetailsString

public String toDetailsString()

flagsDefault

public long flagsDefault(boolean forward,
                         boolean backward)

reverseFlags

public long reverseFlags(long flags)

Reverse flags, to do so all encoders are called.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

handleNodeTags

public long handleNodeTags(ReaderNode node)

Analyze tags on osm node. Store node tags (barriers etc) for later usage while parsing way.

setEnableInstructions

public EncodingManager setEnableInstructions(boolean enableInstructions)

setPreferredLanguage

public EncodingManager setPreferredLanguage(String preferredLanguage)

applyWayTags

public void applyWayTags(ReaderWay way,
                         EdgeIteratorState edge)

fetchEdgeEncoders

public List<FlagEncoder> fetchEdgeEncoders()

The returned list is never empty.

needsTurnCostsSupport

public boolean needsTurnCostsSupport()
