Class ForceCoordinateSystemIterator

Object

ForceCoordinateSystemIterator

All Implemented Interfaces:

Closeable, AutoCloseable, Iterator<SimpleFeature>, SimpleFeatureIterator, FeatureIterator<SimpleFeature>

public class ForceCoordinateSystemIterator
extends Object
implements SimpleFeatureIterator, Iterator<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().getCoordinateSystem();

 assertEquals( forceCS, newCS );

Method Detail

getFeatureType

public SimpleFeatureType getFeatureType()

See Also:

FeatureReader.getFeatureType()

next

public SimpleFeature next()
                   throws NoSuchElementException

Description copied from interface: FeatureIterator

Get the next Feature in this iteration.

Specified by:

next in interface Iterator<SimpleFeature>

Specified by:

next in interface FeatureIterator<SimpleFeature>

Returns:

The next Feature

Throws:

NoSuchElementException - If no more Features exist.

See Also:

FeatureReader.next()

hasNext

public boolean hasNext()

Description copied from interface: FeatureIterator

Does another Feature exist in this Iteration.

Iterator defin: Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<SimpleFeature>

Specified by:

hasNext in interface FeatureIterator<SimpleFeature>

Returns:

true if more Features exist, false otherwise.

See Also:

FeatureReader.hasNext()

remove

public void remove()

Specified by:

remove in interface Iterator<SimpleFeature>

close

public void close()

Description copied from interface: FeatureIterator

Closes this iterator and releases any system resources associated with it.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface FeatureIterator<SimpleFeature>

FeatureReader.close()
