Package noaa.coastwatch.util.chunk

Class ResamplingOperation

java.lang.Object

noaa.coastwatch.util.chunk.ResamplingOperation

All Implemented Interfaces:

ChunkOperation

public class ResamplingOperation
extends Object
implements ChunkOperation

The ResamplingOperation class performs a data resampling operation between pairs of ChunkProducer instances and ChunkConsumer instances. A ResamplingMapFactory is used to create ResamplingMap instances for a given chunk in the consumers' chunking scheme. Consumers are all assumed to have the same chunking scheme, so that resampling can be performed on each chunk in the consumers using the same resampling map. If a given position in the consumer scheme has no valid resampling map, no operation is performed.

Since:

3.5.0

ResamplingOperation

public ResamplingOperation(List<ChunkProducer> producerList,
 List<ChunkConsumer> consumerList,
 ResamplingMapFactory mapFactory)

Creates a new chunk computation from the specified components.

Parameters:

producerList - the list of producers that supply chunks to remap.

consumerList - the list of corresponding consumers that handle the remapped chunks, must be the same length as the producer list.

mapFactory - the factory that creates instances of maps for coordinate mapping.

Throws:

IllegalStateException - if the consumer and producer lists have different sizes.
