Package uk.ac.rdg.resc.edal.feature

Class MapFeature

java.lang.Object

uk.ac.rdg.resc.edal.feature.AbstractDiscreteFeature<HorizontalPosition,GridCell2D>

uk.ac.rdg.resc.edal.feature.MapFeature

All Implemented Interfaces:

Serializable, DiscreteFeature<HorizontalPosition,GridCell2D>, Feature<HorizontalPosition>

public class MapFeature
extends AbstractDiscreteFeature<HorizontalPosition,GridCell2D>
implements Serializable

An implementation of a Feature whose domain is a DiscreteHorizontalDomain. This will be returned from any readMapData operations, and can be passed to plotting routines. Note that the purpose of this Feature is to read data onto a discrete grid regardless of the original domain of the data. The main use case is in extracting onto a grid which defines an image - i.e. each GridCell2D in the domain will map exactly onto a single pixel.

Method Detail

getValues

public Array2D<Number> getValues(String paramId)

Description copied from interface: DiscreteFeature

Gets the array of values for the given parameter. The shape of this array must match the shape of the array of domain objects (from DiscreteDomain.getDomainObjects()).

Specified by:

getValues in interface DiscreteFeature<HorizontalPosition,GridCell2D>

Overrides:

getValues in class AbstractDiscreteFeature<HorizontalPosition,GridCell2D>

Parameters:

paramId - The identifier from the Feature.getVariableIds() set of parameter IDs.

Returns:

the list of values for the requested member

getDomain

public MapDomain getDomain()

Description copied from interface: DiscreteFeature

Specified by:

getDomain in interface DiscreteFeature<HorizontalPosition,GridCell2D>

Specified by:

getDomain in interface Feature<HorizontalPosition>

Overrides:

getDomain in class AbstractDiscreteFeature<HorizontalPosition,GridCell2D>

Returns:

the domain of the values contained with the feature. May not return null
