Constructor Detail

IlvSDOLayer

public IlvSDOLayer(IlvSDOConnection connection,
                   String layerName)
            throws SQLException

Initializes an instance of IlvSDOLayer that will load the data from the specified layer name. The tiles are equivalent to the SDO tiles.

Parameters:

connection - An open connection to the SDO database

layerName - The name of the SDO layer, in the following form: layerName or user.layerName

Throws:

SQLException - if an error occurs during the layer initialization.

IlvSDOLayer

public IlvSDOLayer(IlvSDOConnection connection,
                   String layerName,
                   IlvTileCache cache)
            throws SQLException

Initializes an instance of IlvSDOLayer that will load the data from the specified layer name. The tiles are equivalent to the SDO tiles.

Parameters:

connection - An open connection to the SDO database

layerName - The name of the SDO layer, in the following form: layerName or user.layerName.

cache - The object that manages the release of invisible tiles.

Throws:

SQLException - if an error occurs during the layer initialization.

IlvSDOLayer

public IlvSDOLayer(IlvSDOConnection connection,
                   IlvSDOTileLoader sdoTileLoader,
                   IlvTileCache cache)
            throws SQLException

Initializes an instance of IlvSDOLayer that loads the data with the specified tile loader.

Parameters:

connection - An open connection to the SDO database

sdoTileLoader - The tile loader that generates the SQL queries and defines the size of the tiling grid

cache - The object that manages the release of invisible tiles

Throws:

SQLException - if an error occurs during the layer initialization.

IlvSDOLayer

public IlvSDOLayer(IlvSDOConnection connection,
                   IlvSDOTileLoader sdoTileLoader,
                   IlvTileCache cache,
                   int mode)
            throws SQLException

Initializes an instance of IlvSDOLayer that loads the data with the specified tile loader.

Parameters:

connection - An open connection to the SDO database

sdoTileLoader - The tile loader that generates the SQL queries

cache - The object that manages the release of invisible tiles

mode - to specify whether to use an indexed tile grid (INDEXED_MODE, the behavior of previous versions) to a list of user-specified IlvFreeTile instances (FREE_MODE).

Throws:

SQLException

Since:

JViews 7.5

IlvSDOLayer

public IlvSDOLayer(IlvInputStream stream)
            throws IlvReadFileException

Reads the layer from an IlvInputStream.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - if an error occurs while reading.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the object to an IlvOutputStream. This method also writes its IlvSDOTileLoader, which must be persistent.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvTiledLayer

Parameters:

stream - the output stream

Throws:

IOException - if an errors occurs while writing.

setFeatureRenderer

public void setFeatureRenderer(IlvFeatureRenderer renderer)

Sets the feature renderer used to create graphic objects representing the SDO geometries.

getFeatureRenderer

public IlvFeatureRenderer getFeatureRenderer()

Returns the feature renderer used to create graphic objects representing the SDO geometries. By default, it is an IlvDefaultFeatureRenderer.

getConnection

public IlvSDOConnection getConnection()

Returns the IlvSDOConnection of this layer.
