Class ForceCoordinateSystemFeatureReader

Object
  extended by ForceCoordinateSystemFeatureReader
All Implemented Interfaces:
FeatureReader<SimpleFeatureType,SimpleFeature>

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().getCoordianteSystem();
 
 CoordinateReferenceSystem newCS =
     reader.getFeatureType().getDefaultGeometry().getCoordianteSystem();
 
 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 interface FeatureReader<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 interface FeatureReader<SimpleFeatureType,SimpleFeature>
Returns:
The next feature in the reader.
Throws:
IOException - If an error occurs reading the Feature.
IllegalAttributeException - If the attributes read do not comply with the FeatureType.
NoSuchElementException - If there are no more Features in the Reader.
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 interface FeatureReader<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 interface FeatureReader<SimpleFeatureType,SimpleFeature>
Throws:
IOException - DOCUMENT ME!
See Also:
FeatureReader.close()
