LuciadLightspeedClass TLcyGXYAsynchronousLayerDecoder

java.lang.Object

com.luciad.lucy.map.asynchronous.TLcyGXYAsynchronousLayerDecoder

All Implemented Interfaces:

ILcdGXYLayerDecoder

public class TLcyGXYAsynchronousLayerDecoder
extends Object
implements ILcdGXYLayerDecoder

Asynchronous layer decoder, wrapping around an existing layer decoder. It allows to easily convert a layer decoder into a layer decoder that supports asynchronous painting: the wrapper enables asynchronous painting for the wrapped decoder's created layers.

Constructor Detail

TLcyGXYAsynchronousLayerDecoder

public TLcyGXYAsynchronousLayerDecoder(ILcyLucyEnv aLucyEnv,
                                       ILcdGXYLayerDecoder aLayerDecoder,
                                       ILcdFilter aAsynchronousLayerFilter)

Creates a new layer workspace codec.

Parameters:

aLucyEnv - Lucy environment

aLayerDecoder - existing decoder to wrap. Created layers will be made asynchronous.

aAsynchronousLayerFilter - the filter to use to determine if a created layer should be painted asynchronously. If null, all created layers are painted asynchronously.

Method Detail

getDisplayName

public String getDisplayName()

Description copied from interface: ILcdGXYLayerDecoder

Returns the display name of this encoder.

Specified by:

getDisplayName in interface ILcdGXYLayerDecoder

Returns:

the display name of this encoder.

canDecodeGXYLayer

public boolean canDecodeGXYLayer(ILcdModel aModel,
                                 String aSourceName)

Description copied from interface: ILcdGXYLayerDecoder

Returns true if an ILcdGXYLayer can be decoded from a given source name. Note that implementations using files should verify if the given aSourceName has the correct extension.

Specified by:

canDecodeGXYLayer in interface ILcdGXYLayerDecoder

Parameters:

aModel - The ILcdModel of the ILcdGXYLayer to decode.

aSourceName - The source name of the layer, e.g. a file name or a database name, ...

Returns:

true if an ILcdGXYLayer can be decoded from a given source name, false otherwise.

decodeGXYLayer

public ILcdGXYLayer decodeGXYLayer(ILcdModel aModel,
                                   String aSourceName)
                            throws IOException

This method decodes an ILcdGXYLayer for representing an ILcdModel on an ILcdGXYView. It creates a layer using the wrapped decoder and makes it asynchronous if it is accepted by the asynchronous layer filter, using ALcyAsynchronousPaintFacade.createGXYAsynchronousLayer(com.luciad.view.gxy.ILcdGXYLayer)

Specified by:

decodeGXYLayer in interface ILcdGXYLayerDecoder

Parameters:

aModel - the model for which to create a layer

aSourceName - The source name of the layer, e.g. a file name or a database name, ...

Returns:

a synchronously or asynchronously painted ILcdGXYLayer

Throws:

IOException - In case of an io failure.
