LuciadFusionInterface ILcdGXYLayerEncoder

All Known Implementing Classes:

TLcdFeaturedPointGXYLayerCodec, TLcdFeaturedPolygonGXYLayerCodec, TLcdFeaturedPolylineGXYLayerCodec, TLcdMultilevelRasterGXYLayerCodec, TLcdRasterGXYLayerCodec

public interface ILcdGXYLayerEncoder

This interface models an encoder for ILcdGXYLayer objects. This encoder is responsible for storing the state (e.g. the style) of an ILcdGXYLayer into some persistent storage.

It has a method canEncodeGXYLayer that can be used to check if a given ILcdGXYLayerEncoder can encode a given ILcdGXYLayer. The encoding itself can be performed using encodeGXYLayer.

Method Summary

Modifier and Type	Method and Description
boolean	canEncodeGXYLayer(ILcdGXYLayer aGXYLayer, String aDestinationName) Returns true if the given layer can be encoded to the given destination name.
void	encodeGXYLayer(ILcdGXYLayer aGXYLayer, String aDestinationName) Encodes the given layer to the given destination name.
String	getDisplayName() Returns the display name of this encoder.

Method Detail

getDisplayName

String getDisplayName()

Returns the display name of this encoder.

Returns:

the display name of this encoder.

canEncodeGXYLayer

boolean canEncodeGXYLayer(ILcdGXYLayer aGXYLayer,
                          String aDestinationName)

Returns true if the given layer can be encoded to the given destination name. Note that implementations using files should verify if the given aDestinationName has the correct extension.

Parameters:

aGXYLayer - The layer to be encoded.

aDestinationName - The destination name to encode the layer to, e.g. a file name, a database name, ...

Returns:

true if the given layer can be encoded to the given destination name, false otherwise.

encodeGXYLayer

void encodeGXYLayer(ILcdGXYLayer aGXYLayer,
                    String aDestinationName)
             throws IOException

Encodes the given layer to the given destination name.

The method canEncodeGXYLayer should return true (for the same arguments) before this method is used.

Parameters:

aGXYLayer - The layer to encode.

aDestinationName - The destination name to encode the layer to, e.g. a file name, a database name, ...

Throws:

IOException - In case of io failure.
