LuciadLightspeedInterface ILcdEarthPreprocessorProgressListener

public interface ILcdEarthPreprocessorProgressListener

A listener that receives progress notifications from TLcdEarthTileRepositoryPreprocessor. This interface also allows keeping track of the preprocessing progress and flag a stop condition to cancel the preprocessing.

void	levelComplete() Called when the repository preprocessor has completed processing the current level.
void	levelStarted(int aLevel) Called when the repository preprocessor starts processing a different level.
void	preprocessingComplete() Called when the preprocessing has completed.
void	preprocessingStarted(ILcdEarthTileSet aTileSet, ILcdEarthTileSetCoverage[] aCoverages, int aNumLevels, ILcdEarthAsset[] aAssets, long[] aNumAssetTiles, long[] aNumTilesLeft) Called when the tile preprocessing starts.

Method Detail

progress

boolean progress(ILcdEarthTileSet aTileSet,
                 ILcdEarthTileSetCoverage[] aCoverages,
                 int aLevel,
                 long aUpdateRegionX,
                 long aUpdateRegionY,
                 long aUpdateRegionWidth,
                 long aUpdateRegionHeight,
                 long aCurrentTileX,
                 long aCurrentTileY)

Called when the repository preprocessor has processed a tile. The aTileCreated parameter indicates whether the tile was created or skipped (i.e. whether it was accepted by the ILcdTileFilter). A return value of false signals a stop condition and causes the preprocessing to abort.

Parameters:

aTileSet - The tileset whose tiles are being preprocessed.

aCoverages - The ILcdEarthTileSetCoverages being preprocessed.

aLevel - The detail level at which tiles are being preprocessed.

aUpdateRegionX - The column index of the lower left corner of the tile region that is being preprocessed.

aUpdateRegionY - The row index of the lower left corner of the tile region that is being preprocessed.

aUpdateRegionWidth - The width of the tile region that is being preprocessed.

aUpdateRegionHeight - The height of the tile region that is being preprocessed.

aCurrentTileX - The column index of the tile that was just preprocessed.

aCurrentTileY - The row index of the tile that was just preprocessed.

Returns:

True if preprocessing may continue, false if it should be aborted.

preprocessingStarted

void preprocessingStarted(ILcdEarthTileSet aTileSet,
                          ILcdEarthTileSetCoverage[] aCoverages,
                          int aNumLevels,
                          ILcdEarthAsset[] aAssets,
                          long[] aNumAssetTiles,
                          long[] aNumTilesLeft)

Called when the tile preprocessing starts.

Parameters:

aTileSet - The tileset whose data will be preprocessed.

aCoverages - The coverages in the tileset that will be preprocessed.

aNumLevels - The total number of levels that will be preprocessed.

aAssets - The list of assets that need preprocessing.

aNumAssetTiles - The number of tiles for each asset that need to be preprocessed.

aNumTilesLeft - The number of tiles for each asset that are not yet preprocessed.

preprocessingComplete

void preprocessingComplete()

Called when the preprocessing has completed.

levelStarted

void levelStarted(int aLevel)

Called when the repository preprocessor starts processing a different level.

Parameters:

aLevel - The level that will be processed.

levelComplete

void levelComplete()

Called when the repository preprocessor has completed processing the current level.

assetStarted

void assetStarted(ILcdEarthAsset aAsset,
                  long aUpdateRegionX,
                  long aUpdateRegionY,
                  long aUpdateRegionWidth,
                  long aUpdateRegionHeight,
                  long aStartX,
                  long aStartY)

Called when the repository preprocessor starts processing a different asset.

Parameters:

aAsset - The asset that will be processed.

aUpdateRegionX - The column index of the lower left corner of the tile region that is being preprocessed.

aUpdateRegionY - The row index of the lower left corner of the tile region that is being preprocessed.

aUpdateRegionWidth - The width of the tile region that is being preprocessed.

aUpdateRegionHeight - The height of the tile region that is being preprocessed.

aStartX - The column index of the first tile that will be preprocessed.

aStartY - The row index of the first tile that will be preprocessed.

assetComplete
