Class ChunkDataFlagger

java.lang.Object
noaa.coastwatch.util.chunk.ChunkDataFlagger
All Implemented Interfaces:
ChunkVisitor
public class ChunkDataFlagger extends Object implements ChunkVisitor
The ChunkDataFlagger class is a visitor that modifies any type of DataChunk instance by flagging specific data values as missing. To use a flagger object, call setMissingData(boolean[]) to pass an array of flag values to use, then pass the flagger object as a visitor to a DataChunk instance. If the chunk has no associated missing value, or the flag array has not been set, the data is not modified.
