💜 LiteIndex - Fast and extensive library for indexing box/area in space by vectors/location/position based on hash indexing.
publicclassMain {publicstaticvoidmain(String[]args) {intSPACE_SIZE =10_000;intAREA_SIZE =80;// create indexSpaceIndex<Area,Location>index =SpaceIndex.<Area,Location>builder() .axisX(location ->location.getX()) .axisZ(location ->location.getZ()) .axisY(location ->location.getY()) .space(area ->area.getMin(),area ->area.getMax()) .indexing(IndexingAlgorithm.calculateOptimal(SPACE_SIZE,AREA_SIZE)) .concurrent(false) .build();// put areas to indexindex.put(newArea(newLocation(0,0,0),newLocation(10,10,10)));index.put(newArea(newLocation(3,3,3),newLocation(7,7,7)));index.put(newArea(newLocation(5,5,5),newLocation(15,15,15)));// fast searchList<Area>areas =index.get(newLocation(5,5,5)); }}
Variables:It's not limit, it's just for optimization and memory saving.
MAP_SIZE- expected maximum size of spaceAREA_SIZE- expected maximum size of area
SpaceIndex builder
axisX- function for gettingX coordinateaxisZ- function for gettingZ coordinateaxisY- function for gettingY coordinatespace- function for gettingmin andmax location from areaindexing- set indexing algorithm (configure forbetter performance)concurrent- set concurrent mode (if you want to use index in multiple threads)
SpaceIndex methods
put- put area to indexget- get areas by locationgetAll- get all areas from indexgetFirst- get first area by locationremove- remove area from indexremoveAll- remove all areas from indexcontains- check if index contains areasize- get size of index
IndexingAlgorithm
calculateOptimal- calculate optimal indexing algorithm for your space and area sizechunk- create indexing algorithm(advanced)
