abstract class SpatialPartitioner extends Partitioner with Serializable

Abstract class for partitioning the 3D space. This class extends the Spark Partitioner class, and any new 3D partitioner must extend in turn the SpatialPartitioner class.

    Gets the partitions which are the neighbors of the partitions which contain the input object.

    Gets the partitions which are the neighbors of the partitions which contain the input object.

    input object for which the neighbors are to be found

    returns

    list of Tuple of neighbor partitions and their index/partition IDs

    Gets the partitions which are the neighbors to the input partition.

    Gets the partitions which are the neighbors to the input partition. Useful when getting secondary neighbors (neighbors to neighbor) of the queryObject.

    containingNode

    The boundary of the Node for which neighbors are to be found.

    containingNodeID

    The index/partition ID of the containingNode

    returns

    list of Tuple of secondary neighbor partitions and their index/partition IDs

    Method to place a spatialObject (could a Point3D, a Sphere, and so on) on a grid.

    Method to place a spatialObject (could a Point3D, a Sphere, and so on) on a grid. In practice it will assign a key (Int) to the spatialObject corresponding the partition index. This method must be specifically implemented for each class extending SpatialPartitioner.

    spatialObject

    : (T<:Shape3D) Object of type T = Shape3D, or any extension like Point3D, Sphere, ...

    returns

    (Iterator[Tuple2[Int, T]]) Iterator over a tuple (Key, Object). Key represents the partition number to which the spatialObject T belongs to.
