EncodedValue uses Math.round(value/factor). This can change the retrieved values for EncodedValues #954
EncodedDoubleValue and EncodedValue requires maxValue/factor to be a natural number #954
default base algorithm for all modes is bidirectional A* (except speed mode)
introduced landmarks based hybrid mode, #780
moving all prepare.xy configs to and e.g. disallow the old
removed deprecated methods in GraphHopper (setCHWeighting, setCHWeightings, getCHWeightings, setCHWeightings, getCHPrepareThreads, setCHPrepareThreads), Path.calcMillis, findID of LocationIndex and all implementations
refactoring to Weighting class, see #807
removed FlagEncoder from parameters as weighting.getFlagEncoder can and is used
all properties with prefix "osmreader." changed to "datareader." and osmreader.osm changed to datareader.file
maven/gradle dependency graphhopper is now splitted into graphhopper-core and graphhopper-reader-osm, i.e. if you previouls depend on 'graphhopper' artificat you should now use graphhopper-reader-osm except environments like Android where you just load the graph and do no import
use GraphHopperOSM as base class instead of GraphHopper
OSM reader separated from core, use new graphhopper-core package
moved subnetwork code into own package com.graphhopper.routing.subnetwork
moved weighting code into own package com.graphhopper.routing.weighting
code format has changed, so it is important to change your PRs too before you merge master, see discussion #770
added snapped points to output JSON for every path
the foot routing is now much smoother and only considers safe paths, to use beautiful roads (i.e. prefer hiking routes etc) use the new 'hike' profiles, see #633
vehicle constants have moved to FlagEncoderFactory
several constants changed to under score notation see #719 with a few breaking changes, e.g. use lower case names for flag encoders or jsonp_allowed instead of the jsonpAllowed annotation
moving all string parameter constants into the Parameters class
no more acceptedRailways set see #662 for more information
web API: content type of gpx export is now application/gpx+xml if not explicitely specified
use instead of prepare.chWeighting e.g. for disabling CH use
GraphHopper class is refactored regarding RoutingAlgorithmFactory in order to fix problem when integrating flexibility routing, most of the CH related stuff is moved into CHAlgoFactoryDecorator, several methods are deprecated to use the methods of the decorator, see #631
WeightingMap is now named HintsMap
use the correct graphHopperFolder as no automatic fallback to 'folder-gh' is happening anymore, see #704
refactored FlagEncoder.handleFerryWay to getFerrySpeed to make it possible to fix #665
removed setWeightLimit as too unspecific for arbitrary weights, use setMaxVisitedNodes instead
missing renames for Path.setEdgeEntry -> setSPTEntry and AbstractAlgorithm.createEdgeEntry -> createSPTEntry
removed methods deprecated in 0.4 and 0.5
renamed EdgeEntry to SPTEntry and AStar.AStarEdge to AStar.AStarEntry
parameter force removed from AbstractFlagEncoder.applyMaxSpeed
GHResponse now wraps multiple PathWrapper; renamed GraphHopper.getPaths to calcPaths as 'get' sounded too cheap; a new method RoutingAlgorithm.calcPaths is added; see #596
moving lgpl licensed file into own submodule graphhopper-tools-lgpl
renaming of Tarjans algorithm class to TarjansSCCAlgorithm
more strict naming for Weighting enforced and more strict matching to select Weighting (equals check), #490
specify the preferred-language for way names during graph import (ISO 639-1 or ISO 639-2)
renaming of getCHWeighting to getCHWeightings due to supporting multiple CH weightings, #623
deprecation of setCHWeighting, please use setCHWeightings instead, #623
Several names have changed see #466, #467, #468
GraphHopper.optimize removed use postProcessing instead
method GraphHopper.getGraph() changed to getGraphHopperStorage()
the interface GraphStorage does no longer extend from the Graph interface. Use GraphHopperStorage (which implements the Graph interface via the base graph) or only Graph instead
now it is necessary to call baseGraph/chGraph.freeze in order to use the chGraph (to simply determine when an edgeId is a shortcut)
LevelGraphStorage is now a GraphHopperStorage with an additional ch graph (CHGraphImpl)
GraphHopperStorage implements now the Graph interface and delegates all necessary methods to the underlying base graph. To do routing you call getGraph(CHGraph.class or Graph.class) where the parameter Graph.class returns the base graph and the behaviour is identical to GraphHopperStorage itself
renamed LevelGraph* to CHGraph*
renamed NoGraphExtension to NoOpExtension
removed visitedNodes method in GraphHopper replaced with per response information: response.getHints().getLong("visited_nodes.sum", 0)
added ability to store hints in GHResponse which will be forwarded to the json too
breaking change in HTTP API: error JSON format changed to be message:"" instead of within info.errors, see updated api documentation
made GHResponse.getMillis, Path.getMillis, GPXEntry.getMillis deprecated, use getTime instead
in AbstractFlagEncoder, parse*() and getStr() are now deprecated, use properties.get* instead
translation key turn changed and merged with left etc into turn_left, turn_right etc
create location index before preparation in the GraphHopper class
encodingManager.getSingle() is removed and flagEncoder list is no longer sorted, the first vehicle is used for CH preparation
removed LocationIndexTreeSC, use new LocationIndexTree(levelGraph.getBaseGraph(), directory) instead
getLevel and setLevel do no longer automatically increase node count, use getNodeAccess.ensureNode for that
normal algorithms are now possible on prepared graph use getBaseGraph, see #116
GHResponse no longer has isFound method, use !hasErrors instead
merged unused Edge class into EdgeEntry
astar and astarbi are now both none-heuristic and take parameters for beeline approximation: astar.approximation=BeelineSimplification|BeelineAccurate or astarbi.approximation=...
making GPX export according to the schema to support import from various tools like basecamp
refactoring: AllEdgesIterator.getMaxId is now named getCount
major change of internal API: moved method "Path RoutingAlgorithm.calcPath(QueryResult,QueryResult)" to a helper method QueryGraph.lookup, call queryResult.getClosestNode for the calcPath(nodeFrom,nodeTo) method
no cachedWays and cachedPoints in Path anymore
Path.findInstruction was moved to InstructionList.find
if start and end point are identical an algorithm will find the path consisting only of one node, one point and one instruction (finish instruction), but without edges
astarbi has new default values for approximation (false) and approximation_factor (1.2) in RoutingAlgorithmFactorySimple
instead of strings use the variables in AlgorithmOptions to specify an algorithm
use RoutingAlgorithmFactorySimple instead of RoutingAlgorithmFactory, also more constistent algorithm preparation handling due to new AlgorithmOptions, therefor removed NoOpAlgorithmPreparation
GHResponse.getXX methods now fail fast (throw an exception) if an error while route calculation occured. See #287
renamed less often used URL parameter 'min_path_precision' to way_point_max_distance which makes it identical to the setWayPointMaxDistance method used for simplification at OSMImport
removed douglas.minprecision from Java API ghRequest.hints => use wayPointMaxDistance instead
encoder.supportTurnCost is replaced by encoder.supports(TurnWeighting.class)
CmdArgs is now a Map<String, String> instead Map<String, Object>. The value will be parsed up on every getXY call, makes storing string vs. object less error-prone
removed GHRequest.getHint, instead use the provided methods in GHRequest.getHints().getXY and GHRequest.getHints().put
important graph incompatibility as properties cannot be loaded. renamed osmreader.bytesForFlags to graph.bytesForFlags, renamed config property osmreader.acceptWay to graph.flagEncoders
default weighting is now fastest, fixing #261
moved method GraphHopper.main into tools module and class, see #250
refactored GraphHopper.createWeighting to accept more than one configuration option, see #237
refactored GraphHopper.disableCHShortcuts to setCHEnable(boolean)
moving the boolean parameter of GraphHopper.setInMemory into a separate method setStoreOnFlush
renaming of GraphHopper.setCHShortcuts to setCHWeighting, as well as the property prepare.chShortcuts to prepare.chWeighting
jsonp is disabled by default. You need to enable it in the, see the
EncodingManager cannot be null in GraphHopperStorage. If you need to parse EncodingManager configuration from existing graph use EncodingManager.create
no reflection done in EncodingManager which improves portability and makes configuration of encoders possible before adding to manager
removed dijkstraNativebi as no performance advantage but maintenance disadvantage and similar to oneToManyDijkstra
to provide context for turn costs we needed to add prevEdgeId into Weighting.calcWeight, see new documentation
with the introduction of lock protection mechanism (see #112) GraphHopper needs always write access, see also #217
new GraphHopper.clean method to remove the graph directory via Java API
introduced prefer bits, now bike uses more bits and 3 bike encoder do not fit into 32 bit anymore, will be fixed later
moved Translation argument into Path.calcInstruction for more fine grained control, instructions are now uncached and GHRequest: new locale parameter
CoordTrig and the like are removed, GHPlace is mostly replaced by GHPoint and so GHRequest has now methods ala addPoint instead
removed isBoth from AbstractFlagEncoder, moved canBeOverwritten and associated test to PrepareEncoder
removed unused directory.rename
refactor edge.copyProperties into copyPropertiesTo to have similar semantics as Graph.copyTo
calcWeight now contains reverse boolean to calculate correct direction dependent weight
completely different web API response format. see docs/web
swapDirections is renamed to reverseFlags (EncodingManager and FlagEncoders)
edgeState.detach has now a reverse parameter, just use false to get previous results
web api: buildDate contains now timezone, algoType is replaced with weighting
dijkstraNative is now dijkstraNativebi
fixed #151
calcWeight now contains reverse boolean to calculate correct direction dependent weight
EncodingManager always takes the encoders in constructor, to force always init
GraphHopper.setMemory(true, true/false) was refactored to GraphHopper.setMemory(true/false), use mmap config via GraphHopper.setMemoryMapped()
incompatible edges => you need to re-import data and/or update the edges file
the instructions of the web response does not contain times (string) but instead millis (long)
PrepareContractionHierarchies.setPeriodicUpdates is now in percentage not in absolute counts
improved bike routing #132, #138, #139, #150
gpx export via API, HTTP (route?type=gpx) and web interface is possible: #113, #136, #141
23 Nov 2013
change inconsistent default settings for contraction hierarchies in the API - see
fixed issues with android:
graphhopper: use maps from 0.2 path; updated maps
mapsforge: use mapsforge-map dependency; merged #461; avoid duplicates otherwise mapsforge-core would be duplicate (?)
refactored/renamed classes and methods:
refactor 'flags' from int to long (still only int is stored)
replacing Graph.edge(a,b,dist,flags) by Graph.edge(a,b).setDistance().setFlags()
FlagEncoder.flags => use FlagEncoder.setProperties or separate setAccess and setSpeed method
renamed LocationIDResult to QueryResult and Location2NodesNtree to LocationIndexTree
renamed Location2IDIndex to LocationIndex
renamed WeightCalculation to Weighting and getWeight to calcWeight
the URL parameter algoType in web module is now deprecated and 'weighting' should be used
removed GHDijkstraHeap, GHDijkstraHeap2
made DistanceCalc into interface (new DistanceCalcEarth implementation)
made GraphStorage into interface (new GraphHopperStorage implementation) move some methods from Graph into GraphStorage -> optimize + node removal stuff -> not necessary in algorithms
incompatible storage layout due to:
pluggable endianness (#103) -> changed default endianess to LITTLE
add highly experimental UnsafeDataAccess to speed up search ~15%
several small bug fixes and improvements
different edge insert
important bug fix for edge retrieval which leads to massive speed up in prepare + CH algos
finally fixed major feature request #27 to allow gps-to-gps queries instead of only junction-to-junction ones.
follow up in #52 and #115
slower but more precise and necessary edge distance calculation
fixed bug #105 for disconnected areas
fix which made CH preparation ~5% faster
more align API for all algorithms. and initCollection is called via 1000 not something depending on the graph size
API changed
case of vehicle now case does not matter
returned distance is in meter now
better i18n support
fixed major bug #102 when removing subnetworks
