Method Details

decodeTileData

public Object decodeTileData(InputStream aSource)
                      throws IOException

Description copied from interface: ILcdEarthTileDataCodec

Decodes tile data from the given input stream. The return value of this method must be an object of the type returned by ILcdEarthTileDataCodec.getDecodedTileFormat().

Specified by:

decodeTileData in interface ILcdEarthTileDataCodec

Parameters:

aSource - the input stream from which to read the tile data

Returns:

the decoded tile data

Throws:

IOException - if the tile data cannot be decoded

encodeTileData

public void encodeTileData(Object aTile,
 OutputStream aOutputStream)
                    throws IOException

Description copied from interface: ILcdEarthTileDataCodec

Encodes tile data to the given output stream. The aTileData parameter must be an object of the type returned by ILcdEarthTileDataCodec.getDecodedTileFormat().

Specified by:

encodeTileData in interface ILcdEarthTileDataCodec

Parameters:

aTile - the tile data to be encoded

aOutputStream - the output stream to which to encode the tile data

Throws:

IOException - if the tile data cannot be encoded

getDecodedTileFormat

public TLcdEarthTileFormat getDecodedTileFormat()

Description copied from interface: ILcdEarthTileDataCodec

Returns the tile data format that this codec can encode or decode. The aTile parameter of encodeTileData() should always be of this type, as should the return value of decodeTileData().

Specified by:

getDecodedTileFormat in interface ILcdEarthTileDataCodec

Returns:

the format of the tile data type that this codec can encode or decode

getEncodedDataFormat

public TLcdEarthTileFormat getEncodedDataFormat()

Description copied from interface: ILcdEarthTileDataCodec

Returns the format in which this codec encodes data. An example could be "JPEG" or "PNG" for image data. The format is used in conjunction with ILcdEarthTileDataCodec.getDecodedTileFormat() to retrieve an appropriate tile data codec for any particular tile.

Specified by:

getEncodedDataFormat in interface ILcdEarthTileDataCodec

Returns:

a format in which this codec encodes data
