Description copied from interface: FeatureReader

Return the FeatureType this reader has been configured to create.

Specified by:

getFeatureType in interface FeatureReader<SimpleFeatureType,SimpleFeature>

Returns:

the FeatureType of the Features this FeatureReader will create.

next

public SimpleFeature next()
                   throws IOException,
                          IllegalAttributeException,
                          NoSuchElementException

Description copied from interface: FeatureReader

hasNext

public boolean hasNext()
                throws IOException

Description copied from interface: FeatureReader

Query whether this FeatureReader has another Feature.

Specified by:

hasNext in interface FeatureReader<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.
