public class DelegateFeatureReader<T extends FeatureType,F extends Feature> extends Object implements FeatureReader<T,F>
A FeatureReader that wraps up a normal FeatureIterator.This class is useful for faking (and testing) the Resource based API against in memory datastructures. You are warned that to complete the illusion that Resource based IO is occuring content will be duplicated.

Method Detail

getFeatureType
public T getFeatureType()
Description copied from interface:FeatureReader
Return the FeatureType this reader has been configured to create.- Specified by:
getFeatureType
in interfaceFeatureReader<T extends FeatureType,F extends Feature>
- Returns:
- the FeatureType of the Features this FeatureReader will create.
-
next
public F next() throws IOException, IllegalAttributeException, NoSuchElementException
Description copied from interface:FeatureReader
Reads the next Feature in the FeatureReader.- Specified by:
next
in interfaceFeatureReader<T extends FeatureType,F extends Feature>
- 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.IllegalAttributeException
-
hasNext
public boolean hasNext() throws IOException
Description copied from interface:FeatureReader
Query whether this FeatureReader has another Feature.- Specified by:
hasNext
in interfaceFeatureReader<T extends FeatureType,F extends Feature>
- 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.
-
close
public void close() throws IOException
Description copied from interface:FeatureReader
Release the underlying resources associated with this stream.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Specified by:
close
in interfaceFeatureReader<T extends FeatureType,F extends Feature>
- Throws:
IOException
- if an I/O error occurs
