Constructor Details

SyntheticIntChunkProducer

public SyntheticIntChunkProducer(ChunkingScheme scheme,
 IntBinaryOperator function)

Creates a new producer.

Parameters:

scheme - the chunking scheme to use for this producer.

function - the integer function for this producer that maps (row, column) to an int value.

Method Details

getExternalType

public DataChunk.DataType getExternalType()

Description copied from interface: ChunkProducer

Gets the external type of chunks produced by this producer.

Specified by:

getExternalType in interface ChunkProducer

Returns:

the external data type.

See Also:

• DataChunk.getExternalType()

getChunk

public DataChunk getChunk(ChunkPosition pos)

Description copied from interface: ChunkProducer

Produces a data chunk.

Specified by:

getChunk in interface ChunkProducer

Parameters:

pos - the position of the data chunk to produce.

Returns:

the data chunk.

getNativeScheme

public ChunkingScheme getNativeScheme()

Description copied from interface: ChunkProducer

Gets the native chunking scheme for chunks obtained from this producer. Calls to ChunkProducer.getChunk(noaa.coastwatch.util.chunk.ChunkPosition) are optimized to use chunk positions obtained from the native scheme.

Specified by:

getNativeScheme in interface ChunkProducer

Returns:

the native chunking scheme used by this producer, or null if no native chunking scheme is used.

getPrototypeChunk

public DataChunk getPrototypeChunk()

Description copied from interface: ChunkProducer

Gets a prototype chunk for this producer. Chunks received from the ChunkProducer.getChunk(noaa.coastwatch.util.chunk.ChunkPosition) method conform to the prototype.

Specified by:

getPrototypeChunk in interface ChunkProducer

Returns:

a prototype chunk for chunks produced by this producer.
