Methods in org.heigit.bigspatialdata.oshdb.api.mapreducer that return MapReducer

Modifier and Type	Method and Description
MapReducer<X>	MapReducer.areaOfInterest(OSHDBBoundingBox bboxFilter) Set the area of interest to the given bounding box.
<P extends org.locationtech.jts.geom.Geometry & org.locationtech.jts.geom.Polygonal> MapReducer<X>	MapReducer.areaOfInterest(P polygonFilter) Set the area of interest to the given polygon.
protected abstract MapReducer<X>	MapReducer.copy()
MapReducer<X>	MapReducer.filter(SerializablePredicate<X> f) Adds a custom arbitrary filter that gets executed in the current transformation chain.
<R> MapReducer<R>	MapReducer.flatMap(SerializableFunction<X,Iterable<R>> flatMapper) Set an arbitrary `flatMap` transformation function, which returns list with an arbitrary number of results per input data entry.
MapReducer<List<X>>	MapReducer.groupByEntity() Groups the input data (osm entity snapshot or contributions) by their respective entity's ids before feeding them into further transformation functions.
MapReducer<X>	MapReducer.keytables(OSHDBJdbc keytables) Sets the keytables database to use in the calculations to resolve strings (osm tags, roles) into internally used identifiers.
<R> MapReducer<R>	MapReducer.map(SerializableFunction<X,R> mapper) Set an arbitrary `map` transformation function.
static MapReducer<OSMContribution>	OSMContributionView.on(OSHDBDatabase oshdb)
static MapReducer<OSMEntitySnapshot>	OSMEntitySnapshotView.on(OSHDBDatabase oshdb)
MapReducer<X>	MapReducer.osmEntityFilter(SerializablePredicate<OSMEntity> f) Adds a custom arbitrary filter that gets executed for each osm entity and determines if it should be considered for this analyis or not.
MapReducer<X>	MapReducer.osmTag(Collection<? extends OSMTagInterface> tags) Adds an osm tag filter: The analysis will be restricted to osm entities that have at least one of the supplied tags (key=value pairs or key=*).
MapReducer<X>	MapReducer.osmTag(OSMTagInterface tag) Adds an osm tag filter: The analysis will be restricted to osm entities that have this tag key (with an arbitrary value), or this tag key and value.
MapReducer<X>	MapReducer.osmTag(String key) Adds an osm tag filter: The analysis will be restricted to osm entities that have this tag key (with an arbitrary value).
MapReducer<X>	MapReducer.osmTag(String key, Collection<String> values) Adds an osm tag filter: The analysis will be restricted to osm entities that have this tag key and one of the given values.
MapReducer<X>	MapReducer.osmTag(String key, Pattern valuePattern) Adds an osm tag filter: The analysis will be restricted to osm entities that have a tag with the given key and whose value matches the given regular expression pattern.
MapReducer<X>	MapReducer.osmTag(String key, String value) Adds an osm tag filter: The analysis will be restricted to osm entities that have this tag key and value.
MapReducer<X>	MapReducer.osmType(Set<OSMType> typeFilter) Limits the analysis to the given osm entity types.
MapReducer<X>	MapReducer.tagInterpreter(TagInterpreter tagInterpreter) Sets the tagInterpreter to use in the analysis.
MapReducer<X>	MapReducer.timestamps(OSHDBTimestampList tstamps) Set the timestamps for which to perform the analysis.
MapReducer<X>	MapReducer.timestamps(String isoDate) Sets a single timestamp for which to perform the analysis at.
MapReducer<X>	MapReducer.timestamps(String isoDateStart, String isoDateEnd) Sets two timestamps (start and end date) for which to perform the analysis.
MapReducer<X>	MapReducer.timestamps(String isoDateStart, String isoDateEnd, OSHDBTimestamps.Interval interval) Set the timestamps for which to perform the analysis in a regular interval between a start and end date.
MapReducer<X>	MapReducer.timestamps(String isoDateFirst, String isoDateSecond, String... isoDateMore) Sets multiple arbitrary timestamps for which to perform the analysis.
