Constructor Detail

SpatialCommonIndexedBinningStrategy

public SpatialCommonIndexedBinningStrategy()

Create a binning strategy using a small number of bins. Usage of this method is not recommended, if you are to use this, it should be through serialization.

SpatialCommonIndexedBinningStrategy

public SpatialCommonIndexedBinningStrategy(SpatialBinningType type,
                                           int precision,
                                           boolean useCentroidOnly)

SpatialCommonIndexedBinningStrategy

public SpatialCommonIndexedBinningStrategy(SpatialBinningType type,
                                           int precision,
                                           boolean useCentroidOnly,
                                           String geometryFieldName)

Parameters:

type - S2, H3, or GeoHash

precision - the resolution/length of the hash

useCentroidOnly - desired behavior for complex geometry such as lines and polygons whether to just aggregate one hash value based on the centroid or to apply the aggregation to all overlapping centroids

geometryFieldName - The field name of the geometry used in a given CommonIndexedPersistenceEncoding entry. For more documentation on this behavior, see new GeohashBinningStrategy(int).

Method Detail

getGeometry

public org.locationtech.jts.geom.Geometry getGeometry(DataTypeAdapter<CommonIndexedPersistenceEncoding> adapter,
                                                      CommonIndexedPersistenceEncoding entry)

Description copied from class: SpatialBinningStrategy

Extract the geometry from the entry.

entry - The entry that will be binned using this strategy.

Returns:

The geometry object in the entry, or null if no geometry is found.
