Constructor Detail

FeatureCollectionData

public FeatureCollectionData(List<FeatureCollection> transformableData)
                      throws IllegalArgumentException

Creates a data instance which handles feature collections.

Parameters:

transformableData - to transform

Throws:

IllegalArgumentException - if either one of the crs's are null.

Method Detail

doTransform

public void doTransform(CoordinateSystem sourceCRS,
                        CoordinateSystem targetCRS,
                        boolean enableLogging)
                 throws OGCWebServiceException

Description copied from class: TransformableData

This function should implement the transforming of the underlying data.

Specified by:

doTransform in class TransformableData<FeatureCollection>

Parameters:

sourceCRS - of the incoming points

targetCRS - of the outgoing points

enableLogging - if true the implementing class should log all transformations.

Throws:

OGCWebServiceException - if an exception occurs while transforming.

doTransform

public void doTransform(Transformation transformation,
                        boolean enableLogging)
                 throws OGCWebServiceException

Description copied from class: TransformableData

This function should implement the transforming of the underlying data.

Specified by:

doTransform in class TransformableData<FeatureCollection>

Parameters:

transformation - to use for the transform.

enableLogging - if true the implementing class should log all transformations.

Throws:

OGCWebServiceException - if an exception occurs while transforming.

getTransformedData

public List<FeatureCollection> getTransformedData()

Specified by:

getTransformedData in class TransformableData<FeatureCollection>

Returns:

the transformed data as a list of the overriding class implementation, for example Geometry (GeometyData), or Point3d (SimpleData).

parseFeatureCollection

public static FeatureCollectionData parseFeatureCollection(String url)

Try to load the featureCollection from a given url, and puts the result into a FeatureCollectionData object.

Parameters:

url - to load the data from.

Returns:

a loaded feature collection or null if no file could be loaded.
