next
public SimpleFeature next() throws IOException, IllegalAttributeException, NoSuchElementException
Description copied from interface:FeatureReader
Reads the next Feature in the FeatureReader.- Specified by:
next
in interfaceFeatureReader<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.IllegalAttributeException
-

protected SimpleFeatureType createSchema() throws SchemaException
- Throws:
SchemaException

getFeatureType
public SimpleFeatureType getFeatureType()
Description copied from interface:FeatureReader
Return the FeatureType this reader has been configured to create.- Specified by:
getFeatureType
in interfaceFeatureReader<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 interfaceFeatureReader<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.
