Class PointCloud


  • @Equality
    public class PointCloud
    extends java.lang.Object
    Represents an unordered set of data positions forming part of a plot. An iterator over the points is provided. Instances of this class may also be compared for equality: if instances compare equal, the iterators will dispense the same positions, though not necessarily in the same order.

    The unordered semantics of this class is imposed by the equality requirement. Most of the ordering could be restored by rewording the contract a bit differently if that becomes useful, but at time of writing it's not needed.

    • Constructor Detail

      • PointCloud

        public PointCloud​(SubCloud[] subClouds)
        Constructs a point cloud from an array of subclouds. The order of the items in the array may determine the sequence of point iteration, but does not affect equality with respect to other instances.
        Parameters:
        subClouds - array of cloud components
      • PointCloud

        public PointCloud​(SubCloud subCloud)
        Constructs a point cloud from a single subcloud.
        Parameters:
        subCloud - cloud component
    • Method Detail

      • createDataPosSupplier

        public java.util.function.Supplier<CoordSequence> createDataPosSupplier​(DataStore dataStore)
        Returns an iterable over data positions. Iteration is over dataDimCount-element coordinate arrays giving position in data space.
        Parameters:
        dataStore - data storage object
        Returns:
        iterable over usable data positions
      • getSubClouds

        public SubCloud[] getSubClouds()
        Returns an array of the subclouds in this point cloud.
        Returns:
        subcloud array
