                     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

SchemaException
Method Detail

next

public org.opengis.feature.simple.SimpleFeature next()
                                              throws java.io.IOException,
                                                     IllegalAttributeException,
                                                     java.util.NoSuchElementException
Description copied from interface: FeatureReader
Reads the next Feature in the FeatureReader.

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

createSchema

protected org.opengis.feature.simple.SimpleFeatureType createSchema()
                                                             throws SchemaException
Throws:
SchemaException

readFeature

protected org.opengis.feature.simple.SimpleFeature readFeature(AttributeReader atts)
                                                        throws IllegalAttributeException,
                                                               java.io.IOException
Throws:
IllegalAttributeException
java.io.IOException

close

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

Specified by:
close in interface FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>
Throws:
java.io.IOException - DOCUMENT ME!

getFeatureType

public org.opengis.feature.simple.SimpleFeatureType getFeatureType()
Description copied from interface: FeatureReader
Return the FeatureType this reader has been configured to create.

Specified by:
getFeatureType in interface FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>
Returns:
the FeatureType of the Features this FeatureReader will create.

hasNext

public boolean hasNext()
                throws java.io.IOException
Description copied from interface: FeatureReader
Query whether this FeatureReader has another Feature.

Specified by:
hasNext in interface FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.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:
java.io.IOException - If an error occurs determining if there are more Features.
