public class ForceCoordinateSystemFeatureReader extends Object implements FeatureReader<SimpleFeatureType,SimpleFeature>
ForceCoordinateSystemFeatureReader provides a CoordinateReferenceSystem for FeatureTypes.ForceCoordinateSystemFeatureReader is a wrapper used to force GeometryAttributes to a user supplied CoordinateReferenceSystem rather then the default supplied by the DataStore.
Example Use:
ForceCoordinateSystemFeatureReader reader = new ForceCoordinateSystemFeatureReader( originalReader, forceCS ); CoordinateReferenceSystem originalCS = originalReader.getFeatureType().getDefaultGeometry().getCoordinateSystem(); CoordinateReferenceSystem newCS = reader.getFeatureType().getDefaultGeometry().getCoordinateSystem(); assertEquals( forceCS, newCS );

Method Detail

getFeatureType
public SimpleFeatureType getFeatureType()
Description copied from interface:FeatureReader
Return the FeatureType this reader has been configured to create.- Specified by:
getFeatureType
in interfaceFeatureReader<SimpleFeatureType,SimpleFeature>
- Returns:
- the FeatureType of the Features this FeatureReader will create.
- See Also:
FeatureReader.getFeatureType()
-
next
public SimpleFeature next() throws IOException, IllegalAttributeException, NoSuchElementException
Description copied from interface:FeatureReader
Reads the next Feature in the FeatureReader.- Specified by:
next
in interfaceFeatureReader<SimpleFeatureType,SimpleFeature>
- Returns:
- The next feature in the reader.
- Throws:
IOException
- If an error occurs reading the Feature.NoSuchElementException
- If there are no more Features in the Reader.IllegalAttributeException
- See Also:
FeatureReader.next()
-
hasNext
public boolean hasNext() throws IOException
Description copied from interface:FeatureReader
Query whether this FeatureReader has another Feature.- Specified by:
hasNext
in interfaceFeatureReader<SimpleFeatureType,SimpleFeature>
- Returns:
- True if there are more Features to be read. In other words, true if calls to next would return a feature rather than throwing an exception.
- Throws:
IOException
- If an error occurs determining if there are more Features.- See Also:
FeatureReader.hasNext()
-
close
public void close() throws IOException
Description copied from interface:FeatureReader
Release the underlying resources associated with this stream.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Specified by:
close
in interfaceFeatureReader<SimpleFeatureType,SimpleFeature>
- Throws:
IOException
- if an I/O error occurs- See Also:
FeatureReader.close()
