public interface FeatureReader<T extends FeatureType,F extends Feature>
The low-level interface for reading Features. Will use the underlying AttributeReader and the given FeatureType to create new Features.
Typical use is as follows:
FeatureReader reader = null;
try{
for( reader = data.getFeatureReader( filter ); reader.hasNext(); ){
f = reader.next();
...
}
}
catch (IOException problem){
...
}
finally {
if( reader != null ){
try {
reader.close();
}
catch( IOException eek){
}
}
}
