Class ForceCoordinateSystemFeatureResults

Object

AbstractFeatureCollection

ForceCoordinateSystemFeatureResults

All Implemented Interfaces:

SimpleFeatureCollection, FeatureCollection<SimpleFeatureType,SimpleFeature>

public class ForceCoordinateSystemFeatureResults
extends AbstractFeatureCollection

ForceCoordinateSystemFeatureResults 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:

 ForceCoordinateSystemFeatureResults results =
     new ForceCoordinateSystemFeatureResults( originalResults, forceCS );

 CoordinateReferenceSystem originalCS =
     originalResults.getFeatureType().getDefaultGeometry().getCoordinateSystem();

 CoordinateReferenceSystem newCS =
     reader.getFeatureType().getDefaultGeometry().getCoordinateSystem();

 assertEquals( forceCS, newCS );

Method Detail

openIterator

public Iterator<SimpleFeature> openIterator()

Description copied from class: AbstractFeatureCollection

Factory method used to open an iterator over collection contents for use by AbstractFeatureCollection.iterator() and AbstractFeatureCollection.features().

If you return an instance of FeatureIterator some effort is taken to call the FeatureIterator.close() internally, however we cannot offer any assurance that client code using AbstractFeatureCollection.iterator() will perform the same check.

Specified by:

openIterator in class AbstractFeatureCollection

Returns:

Iterator over collection contents

closeIterator

public void closeIterator(Iterator close)

size

public int size()

Description copied from class: AbstractFeatureCollection

Returns the number of elements in this collection.

Specified by:

size in interface FeatureCollection<SimpleFeatureType,SimpleFeature>

Specified by:

size in class AbstractFeatureCollection

Returns:

Number of items, or Interger.MAX_VALUE

See Also:

Collection.size()

getBounds

public ReferencedEnvelope getBounds()

Description copied from class: AbstractFeatureCollection

Subclasses need to override this.

Specified by:

getBounds in interface FeatureCollection<SimpleFeatureType,SimpleFeature>

Specified by:

getBounds in class AbstractFeatureCollection

Returns:

An Envelope containing the total bounds of this collection.

See Also:

org.geotools.data.FeatureResults#getBounds()

getOrigin

public FeatureCollection<SimpleFeatureType,SimpleFeature> getOrigin()

Returns the feature results wrapped by this ForceCoordinateSystemFeatureResults

accepts

public void accepts(FeatureVisitor visitor,
                    ProgressListener progress)
             throws IOException

Description copied from interface: FeatureCollection

Visit the contents of a feature collection.

The order of traversal is dependent on the FeatureCollection implementation; some collections are able to make efficient use of an internal index in order to quickly visit features located in the same region.

Specified by:

accepts in interface FeatureCollection<SimpleFeatureType,SimpleFeature>

Overrides:

accepts in class AbstractFeatureCollection

Parameters:

visitor - Closure applied to each feature in turn.

progress - Used to report progress, may be used to interrupt the operation

Throws:

IOException

canDelegate

protected boolean canDelegate(FeatureVisitor visitor)
