Abstract Value Members

  1. abstract def placeObject[T <: Geometry](spatialObject: T): Iterator[(Integer, T)]

    Given a geometry, returns a list of partitions it overlaps.

    Given a geometry, returns a list of partitions it overlaps.

    For points, returns exactly one partition as long as grid type is non-overlapping. For other geometry types or for overlapping grid types, may return multiple partitions.

    Equal and Hilbert partitioning methods have necessary properties to support de-dup.

    Equal and Hilbert partitioning methods have necessary properties to support de-dup. These methods provide non-overlapping partition extents and not require overflow partition as they cover full extent of the RDD. However, legacy SpatialRDD.spatialPartitioning(otherGrids) method doesn't preserve the grid type making it impossible to reliably detect whether partitioning allows efficient de-dup or not.

    TODO Figure out how to remove SpatialRDD.spatialPartitioning(otherGrids) API. Perhaps, make the implementation no-op and fold the logic into JoinQuery, RangeQuery and KNNQuery APIs.
