Class DataSubset.Tile

java.lang.Object

org.apache.sis.internal.storage.TiledGridCoverage.Snapshot

org.apache.sis.storage.geotiff.DataSubset.Tile

All Implemented Interfaces:

Comparable<DataSubset.Tile>

Enclosing class:

DataSubset

private static final class DataSubset.Tile
extends TiledGridCoverage.Snapshot
implements Comparable<DataSubset.Tile>

Information about a tile to be read. A list of Tile is created and sorted by increasing offsets before the read operation begins, in order to read tiles in the order they are written in the TIFF file.

Since:

1.1

Version:

1.3

Field Details

byteOffset

private final long byteOffset

Value of DataSubset.tileOffsets at index TiledGridCoverage.Snapshot.indexInTileVector. If pixel data are stored in different planes ("banks" in Java2D terminology), then current implementation takes only the offset of the first bank to read. This field contains the value that we want in increasing order.

Constructor Details

Tile

Tile(TiledGridCoverage.AOI domain,
 Vector tileOffsets,
 int[] includedBanks,
 int numTiles)

Stores information about a tile to be loaded.

Parameters:

iterator - the iterator for which to create a snapshot of its current position.

Method Details

copyTileInfo

final void copyTileInfo(Vector source,
 long[] target,
 int[] includedBanks,
 int numTiles)

Copies DataSubset.tileOffsets or DataSubset.tileByteCounts values into the given target array. Values for different planes ("banks" in Java2D terminology) are packed as consecutive values in the given target array.

Parameters:

source - DataSubset.tileOffsets or DataSubset.tileByteCounts.

target - the array where to copy vector values.

numTiles - value of DataSubset.numTiles.

compareTo

public int compareTo(DataSubset.Tile other)

Compares this tile with the specified tile for order in which to perform read operations.

Specified by:

compareTo in interface Comparable<DataSubset.Tile>
