Class ForceCoordinateSystemFeatureReader

Object

ForceCoordinateSystemFeatureReader

All Implemented Interfaces:

Closeable, AutoCloseable, 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().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 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 Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface FeatureReader<SimpleFeatureType,SimpleFeature>

Throws:

IOException - if an I/O error occurs

See Also:

FeatureReader.close()
