Class ForceCoordinateSystemFeatureReader

java.lang.Object
  org.geotools.data.crs.ForceCoordinateSystemFeatureReader

All Implemented Interfaces:

FeatureReader

public class ForceCoordinateSystemFeatureReader

extends java.lang.Object

implements FeatureReader

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 );

                                   throws SchemaException

Builds a new ForceCoordinateSystemFeatureReader

Parameters:

Throws:

SchemaException

java.lang.NullPointerException - DOCUMENT ME!

java.lang.IllegalArgumentException - DOCUMENT ME!

Method Detail

getFeatureType

public FeatureType getFeatureType()

Description copied from interface: FeatureReader

Return the FeatureType this reader has been configured to create.

Specified by:

getFeatureType in interface FeatureReader

Returns:

the FeatureType of the Features this FeatureReader will create.

See Also:

FeatureReader.getFeatureType()

next

public Feature next()
             throws java.io.IOException,
                    IllegalAttributeException,
                    java.util.NoSuchElementException

Description copied from interface: FeatureReader

Reads the next Feature in the FeatureReader.

Specified by:

next in interface FeatureReader

Returns:

The next feature in the reader.

Throws:

java.util.NoSuchElementException - If there are no more Features in the Reader.

IllegalAttributeException - If the attributes read do not comply with the FeatureType.

java.io.IOException - If an error occurs reading the Feature.

See Also:

FeatureReader.next()

hasNext

public boolean hasNext()
                throws java.io.IOException

Description copied from interface: FeatureReader

Query whether this FeatureReader has another Feature.

Specified by:

hasNext in interface FeatureReader

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:

java.io.IOException - If an error occurs determining if there are more Features.

See Also:

FeatureReader.hasNext()

close

public void close()
           throws java.io.IOException

Description copied from interface: FeatureReader

Release the underlying resources associated with this stream.

Specified by:

close in interface FeatureReader

Throws:

java.io.IOException - DOCUMENT ME!

FeatureReader.close()
