Constructor Detail

IlvKMLDataSource

public IlvKMLDataSource(IlvInputStream stream)
                 throws IlvReadFileException

Creates a new IlvKMLDataSource.

Parameters:

stream - The stream to read from.

Throws:

IlvReadFileException

IlvKMLDataSource

public IlvKMLDataSource(String filename)
                 throws MalformedURLException

Constructs an IlvKMLDataSource from the specified file name.

Parameters:

filename - The name of the KML file to read.

Throws:

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

IlvKMLDataSource

public IlvKMLDataSource(URL url)
                 throws IOException

Constructs a IlvKMLDataSource from the specified url.

Parameters:

url - The name of the KML 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.

Specified by:

initFeatureList in class IlvDefaultTilableDataSource

See Also:

IlvDefaultTilableDataSource.initFeatureList()

createFeatureIterator

protected IlvMapReusableFeatureIterator createFeatureIterator(String fileName)
                                                       throws MalformedURLException

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

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

Specified by:

createFeatureIterator in class IlvDefaultTilableDataSource

Parameters:

fileName - file parameter.

Returns:

the data source reader.

Throws:

MalformedURLException

See Also:

IlvDefaultTilableDataSource.createFeatureIterator(java.lang.String)

createFeatureIterator

protected IlvMapReusableFeatureIterator createFeatureIterator(URL url)

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

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

Specified by:

createFeatureIterator in class IlvDefaultTilableDataSource

Parameters:

url - file parameter.

Returns:

the data source reader.

See Also:

IlvDefaultTilableDataSource.createFeatureIterator(java.net.URL)

createDefaultFilter

protected IlvDefaultFeatureFilter createDefaultFilter()

Creates, at construction time, the filter that will be used to separate features into layers. For example, this method can create an IlvDefaultFeatureFilter instance and pass the property used to split features.

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()

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 - A feature value to filter features with.

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

Returns:

The feature iterator.

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this IlvVMAPDataSource to an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvDefaultTilableDataSource

Parameters:

stream - The stream to write to.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.
