Class NestedTable

  • public class NestedTable
extends Object
    Implements "nested table" views of point feature datasets. A NestedTable is initialized with a TableConfig. A NestedTable Table is created after the Tables have been joined, and the leaves identified. It is a single chain of Table objects from child to parent. Highest parent is root. Lowest child is leaf

    A nested table starts with a leaf table (no children), plus all of its parents. There is a "join" for each child and parent.

    Assumes that we have Tables that can be iterated over with a StructureDataIterator. A parent-child join assumes that for each row of the parent, a StructureDataIterator exists that iterates over the rows of the child table for that parent.

    Nested Tables must be put in canonical form, based on feature type:

    1. point : obsTable
    2. station : stnTable -> obsTable
    3. traj : trajTable -> obsTable
    4. profile : profileTable -> obsTable
    5. stationProfile : stnTable -> profileTable -> obsTable
    6. section : sectionTable -> trajTable -> obsTable
