Constructor Detail

PreGeneralizedFeatureReader

public PreGeneralizedFeatureReader(SimpleFeatureType featureTyp,
                                   int[] indexMapping,
                                   FeatureReader<SimpleFeatureType,SimpleFeature> backendReader,
                                   String geomPropertyName,
                                   String backendGeomPropertyName)
Method Detail

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!

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.

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.

next

public SimpleFeature next()
                   throws IOException,
                          IllegalArgumentException,
                          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.
NoSuchElementException - If there are no more Features in the Reader.
IllegalArgumentException
