close
Description copied from interface:FeatureReader
Release the underlying resources associated with this stream.- Specified by:

- Specified by:
close
in interfaceFeatureReader<SimpleFeatureType,
SimpleFeature> - Throws:
IOException
- if an I/O error occurs
-
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
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.
-
next
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
-
getVPFFile
Returns the VPFFile for a particular column. It will only find the first match, but that should be okay because duplicate columns will cause even bigger problems elsewhere.- Parameters:
column
- the column to search for- Returns:
- the VPFFile that owns this column
-
