Method Detail

getFeatureIterator

public IlvMapReusableFeatureIterator getFeatureIterator()

Retrieves the feature iterator used by this data source.

Overrides:

getFeatureIterator in class IlvShapeDataSource

Returns:

The feature iterator.

write

public void write(IlvOutputStream stream)
           throws IOException

Writes an IlvTiledShapeDataSource into an IlvOutputStream

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvShapeDataSource

Parameters:

stream - The stream to write to.

Throws:

IOException

reset

public void reset()

Resets this data source for further use.

Overrides:

reset in class IlvShapeDataSource

start

public void start()
           throws Exception

Starts this data source. As this datasource uses load on demand mechanism, map features are not rendered within this method. Instead, this method creates the tiled layer that will further load shape tiles.

Overrides:

start in class IlvMapDataSource

Throws:

Exception

getTiledLayer

public IlvTiledLayer getTiledLayer()

Returns the IlvTiledLayer created by this data source.

Returns:

the IlvTiledLayer of this data source

initInsertionLayer

protected void initInsertionLayer(IlvMapLayer layer)

Initialize the insertion IlvMapLayer of this datasource. Basically inserts a new IlvTiledLayer in the specified IlvMapLayer.

Overrides:

initInsertionLayer in class IlvMapDataSource

Parameters:

layer - the IlvMapLayer to initialize

toString

public String toString()

Returns the name of the data source.

Overrides:

toString in class IlvMapDataSource

Returns:

the name of the data source.

isMultiThreaded

public boolean isMultiThreaded()

Returns whether the tiled layer created by this data source uses multithreading to load tiles

Returns:

boolean, true if multi threaded, false if not.

Since:

JViews 8.0

setMultiThreaded

public void setMultiThreaded(boolean threaded)

Indicates whether the tiled layer created by this data source will use multithreading to load tiles. This method must be called before the data source is started.

Parameters:

threaded - boolean, true if multi threaded, false if not.

Since:
