Interface GridValueCell

Show UML class diagram

All Superinterfaces:

ValueObject

@UML(identifier="CV_GridValueCell",
     specification=ISO_19123)
public interface GridValueCell
extends ValueObject

Basis for interpolating within a continuous quadrilateral grid coverage. A GridValueCell is a collection of grid point value pairs with a geometric structure defined by a grid cell.

Since:

GeoAPI 2.1

Method Summary

Set<GridPointValuePair>	getControlValues() Returns the set of grid point-value pairs at the corners of this GridValueCell.
GridCell	getGridCell() Returns the grid cell that defines the structure of the grid point value pairs that support the interpolation of a feature attribute value at a direct position within the grid cell.

Method Detail

getGridCell

@UML(identifier="geometry",
     obligation=MANDATORY,
     specification=ISO_19123)
GridCell getGridCell()

Returns the grid cell that defines the structure of the grid point value pairs that support the interpolation of a feature attribute value at a direct position within the grid cell.

Returns:

The structure of grid points.

Departure from OGC/ISO specification:
ISO defines this method as a specialization of getGeometry(). We can not reflect this association in Java because of incompatible return type.

getControlValues

@UML(identifier="controlValue",
     obligation=MANDATORY,
     specification=ISO_19123)
Set<GridPointValuePair> getControlValues()

Returns the set of grid point-value pairs at the corners of this GridValueCell.

Specified by:

getControlValues in interface ValueObject

Returns:

The control values.
