Class TLcyGXYAsynchronousLayerEncoder

java.lang.Object

com.luciad.lucy.map.asynchronous.TLcyGXYAsynchronousLayerEncoder

All Implemented Interfaces:

ILcdGXYLayerEncoder

public class TLcyGXYAsynchronousLayerEncoder
extends Object
implements ILcdGXYLayerEncoder

Asynchronous layer encoder, wrapping around an existing layer encoder. It allows to easily convert a layer encoder into a layer encoder that supports asynchronous painting.

In particular, it ensures that the encoding does not interfere with asynchronous painting.

Constructor Details

TLcyGXYAsynchronousLayerEncoder

public TLcyGXYAsynchronousLayerEncoder(ILcyLucyEnv aLucyEnv,
 ILcdGXYLayerEncoder aLayerEncoder)

Creates a new layer workspace codec.

Parameters:

aLucyEnv - Lucy environment

aLayerEncoder - existing encoder to wrap. Calls pertaining to an asynchronously painted layer will be delegated using a safe layer.

Method Details

getDisplayName

public String getDisplayName()

Description copied from interface: ILcdGXYLayerEncoder

Returns the display name of this encoder.

Specified by:

getDisplayName in interface ILcdGXYLayerEncoder

Returns:

the display name of this encoder.

canEncodeGXYLayer

public boolean canEncodeGXYLayer(ILcdGXYLayer aGXYLayer,
 String aDestinationName)

Description copied from interface: ILcdGXYLayerEncoder

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.

Specified by:

canEncodeGXYLayer in interface ILcdGXYLayerEncoder

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

public void encodeGXYLayer(ILcdGXYLayer aGXYLayer,
 String aDestinationName)
                    throws IOException

Description copied from interface: ILcdGXYLayerEncoder

Encodes the given layer to the given destination name.

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

Specified by:

encodeGXYLayer in interface ILcdGXYLayerEncoder

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.
