Method Details

getFeatures

SimpleFeatureCollection getFeatures()
                             throws IOException

Description copied from interface: FeatureSource

Retrieves all features in the form of a FeatureCollection.

The following statements are equivalent:

     featureSource.getFeatures();
     featureSource.getFeatures(Filter.INCLUDE);
     featureSource.getFeatures(Query.ALL);
 

Specified by:

getFeatures in interface FeatureSource<SimpleFeatureType,SimpleFeature>

Returns:

features retrieved by the Query

Throws:

IOException - if the underlying data source cannot be accessed.
