Constructor Detail

IlvDAFIFDataSource

public IlvDAFIFDataSource(IlvInputStream stream)
                   throws IlvReadFileException

Creates a new IlvDAFIFDataSource.

Parameters:

stream - The stream to read from.

Throws:

IlvReadFileException

IlvDAFIFDataSource

public IlvDAFIFDataSource(String filename)
                   throws MalformedURLException

Constructs an IlvDAFIFDataSource from the specified file name.

Parameters:

filename - The name of the DAFIF file to read.

Throws:

MalformedURLException - if the path cannot be parsed as a URL.

IlvDAFIFDataSource

public IlvDAFIFDataSource(URL url)
                   throws IOException

Constructs an IlvS57DataSource from the specified URL.

Parameters:

url - The name of the S57 file to read.

Throws:

IOException

Method Detail

initFeatureList

protected void initFeatureList()

Specific initialization done when data source is created. It should be used to retrieve the possible feature codes that the data source can manage. This method reads the DAFIFFeaturesEN.xml resource file.

Specified by:

initFeatureList in class IlvDefaultTilableDataSource

See Also:

IlvDefaultTilableDataSource.initFeatureList()

createFeatureIterator

protected IlvMapReusableFeatureIterator createFeatureIterator(String fileName)
                                                       throws IOException

Method used in IlvDefaultTilableDataSource.IlvDefaultTilableDataSource(String) constructor to build the data source reader. For example:

  protected void createFeatureIterator(String fileName)
  {
    return new IlvS57Reader(fileName);
  }
   

Creates a IlvDAFIFReader

Specified by:

createFeatureIterator in class IlvDefaultTilableDataSource

Parameters:

fileName - The file parameter.

Returns:

The data source reader.

Throws:

IOException

See Also:

IlvDefaultTilableDataSource.createFeatureIterator(java.lang.String)

createFeatureIterator

protected IlvMapReusableFeatureIterator createFeatureIterator(URL url)
                                                       throws IOException

Method used in the IlvDefaultTilableDataSource.IlvDefaultTilableDataSource(URL) constructor to build the data source reader. For example:

  protected void createFeatureIterator(URL urlName)
  {
    return new IlvS57Reader(urlName);
  }
   

Creates a IlvDAFIFReader

Specified by:

createFeatureIterator in class IlvDefaultTilableDataSource

Parameters:

url - The file parameter.

Returns:

The data source reader.

Throws:

IOException

See Also:

IlvDefaultTilableDataSource.createFeatureIterator(java.net.URL)

createDefaultFilter

protected IlvDefaultFeatureFilter createDefaultFilter()

Creates a filter on CODE_PROPERTY_NAME property.

Overrides:

createDefaultFilter in class IlvDefaultTilableDataSource

Returns:

The default feature filter that will be used to separate layers for this data source.

See Also:

IlvDefaultTilableDataSource.createDefaultFilter()

start

public void start()
           throws Exception

Starts this data source. The rendering process is initiated. The map features are read from the reader, graphic objects are rendered and inserted into the manager.

Overrides:

start in class IlvDefaultTilableDataSource

Throws:

Exception

See Also:

IlvDefaultTilableDataSource.start()

createTiledIterator

protected IlvMapRegionOfInterestIterator createTiledIterator(IlvFeatureClassInformation featureValue,
                                                             IlvGeometryClassFilter geometryClass)

Creates an iterator that iterates through the map features for a specific area of interest.

Specified by:

createTiledIterator in class IlvDefaultTilableDataSource

Parameters:

featureValue - The feature value for filtering features.

geometryClass - A subclass of IlvMapGeometry to prevent the mixing of different types of features on the same layer.

Returns:

The feature iterator.

makeLayerName

public String makeLayerName(String name,
                            IlvGeometryClassFilter d)

Creates a layer name from a feature name and a geometry class.

Overrides:

makeLayerName in class IlvDefaultTilableDataSource

Parameters:

name - The feature name.

d - The geometry class.

Returns:

A string to use as a layer name.
