Method Detail

close

public void close()
           throws java.io.IOException
Closes the feature reader

Specified by:
close in interface FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>
Throws:
java.io.IOException - DOCUMENT ME!

getFeatureType

public org.opengis.feature.simple.SimpleFeatureType getFeatureType()
Description copied from interface: FeatureReader
Return the FeatureType this reader has been configured to create.

Specified by:
getFeatureType in interface FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>
Returns:
the FeatureType of the Features this FeatureReader will create.

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<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.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:
java.io.IOException - If an error occurs determining if there are more Features.

next

public org.opengis.feature.simple.SimpleFeature next()
                                              throws java.io.IOException,
                                                     java.lang.IllegalArgumentException,

Returns:
