                     throws SchemaException
Creates a new instance of AbstractFeatureReader

Parameters:
attributeReader - AttributeReader for contents
schema - FeatureType to use, null if not provided
Throws:
SchemaException - If Schema could not be obtained

DefaultFeatureReader

public DefaultFeatureReader(AttributeReader attributeReader)
                     throws SchemaException
Throws:
SchemaException
Method Detail

next

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

Specified by:
next in interface FeatureReader<SimpleFeatureType,SimpleFeature>
Returns:
The next feature in the reader.
Throws:
IOException - If an error occurs reading the Feature.
IllegalAttributeException - If the attributes read do not comply with the FeatureType.
NoSuchElementException - If there are no more Features in the Reader.

createSchema

protected SimpleFeatureType createSchema()
                                  throws SchemaException
Throws:
SchemaException

readFeature

protected SimpleFeature readFeature(AttributeReader atts)
                             throws IllegalAttributeException,
                                    IOException
Throws:
IllegalAttributeException
IOException

close

public void close()
           throws IOException
Description copied from interface: FeatureReader
Release the underlying resources associated with this stream.

Specified by:
close in interface FeatureReader<SimpleFeatureType,SimpleFeature>
Throws:
IOException - DOCUMENT ME!

getFeatureType

public SimpleFeatureType getFeatureType()
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.

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.
