Constructor Details

ALcdEarthTileSetMultilevelRaster

protected ALcdEarthTileSetMultilevelRaster(ILcdEarthTileSet aTileSet)

Creates a multilevel raster wrapper for the given tileset. The first valid coverage in the given tileset will be used to retrieve the raster data.

Parameters:

aTileSet - A tileset.

Throws:

IllegalArgumentException - If no valid coverage is available.

See Also:

• isValidRasterCoverage(com.luciad.earth.tileset.ILcdEarthTileSetCoverage)

ALcdEarthTileSetMultilevelRaster

protected ALcdEarthTileSetMultilevelRaster(ILcdEarthTileSet aTileSet,
 ILcdEarthTileSetCoverage aCoverage)

Creates a multilevel raster wrapper for the given tileset. If the given coverage is not null, it will be used to retrieve the data. Otherwise the first valid coverage is used instead.

Parameters:

aTileSet - A tileset.

aCoverage - The coverage that contains the raster data or null to use the first valid coverage from the given tileset.

Throws:

IllegalArgumentException - If the given coverage is not null and not valid or no valid coverage is available.

See Also:

• isValidRasterCoverage(com.luciad.earth.tileset.ILcdEarthTileSetCoverage)

Method Details

getRasterTileSetCoverage

public ILcdEarthTileSetCoverage getRasterTileSetCoverage()

Returns the data coverage that is used to retrieve the raster data.

Returns:

A data coverage.

getRasterTileSet

public ILcdEarthTileSet getRasterTileSet()

Returns the tileset used to retrieve the raster data.

Returns:

A tileset.

isValidRasterCoverage

protected abstract boolean isValidRasterCoverage(ILcdEarthTileSetCoverage aCoverage)

Returns whether the given coverage is a valid raster coverage for this multi level raster.

Parameters:

aCoverage - An earth coverage.

Returns:

True if the coverage can be used as the raster data source.

createRaster

protected abstract ILcdRaster createRaster(int aLevel)

Creates the raster at the given level.

Parameters:

aLevel - A level.

Returns:

A raster.

getRasterCount

public int getRasterCount()

Specified by:

getRasterCount in interface ILcdMultilevelRaster

Returns:

the number of ILcdRaster objects in this ILcdMultilevelRaster.

getRaster

public ILcdRaster getRaster(int i)

Specified by:

getRaster in interface ILcdMultilevelRaster

Returns:

the ILcdRaster at level aLevel.

insertIntoCache

public void insertIntoCache(Object o,
 Object o1)

Description copied from interface: ILcdCache

Inserts a cache Object corresponding to the given key Object.

Specified by:

insertIntoCache in interface ILcdCache

Parameters:

o - the key Object that will be used to identify the Object. The key must therefore be a unique identifier, typically the caller itself: insertIntoCache(this, ...).

o1 - the Object to be cached.

removeCachedObject

public Object removeCachedObject(Object o)

Description copied from interface: ILcdCache

Looks up and removes the cached Object corresponding to the given key.

Specified by:

removeCachedObject in interface ILcdCache

Parameters:

o - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there was no Object corresponding to the given key.

clearCache

public void clearCache()

Description copied from interface: ILcdCache

Clears the cache.

Specified by:

clearCache in interface ILcdCache

getCachedObject

public Object getCachedObject(Object o)

Description copied from interface: ILcdCache

Looks up and returns the cached Object corresponding to the given key.

Specified by:

getCachedObject in interface ILcdCache

Parameters:

o - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there is no Object corresponding to the given key.
