Class NestedTable

java.lang.Object

ucar.nc2.ft.point.standard.NestedTable

public class NestedTable
extends java.lang.Object

Implements "nested table" views of point feature datasets. A NestedTable is initialized with a TableConfig.

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
