org.geotools.data.oracle
Class OracleFeatureWriter

java.lang.Object
  org.geotools.data.jdbc.JDBCFeatureWriter
      org.geotools.data.jdbc.JDBCTextFeatureWriter
          org.geotools.data.oracle.OracleFeatureWriter

All Implemented Interfaces:

FeatureWriter

public class OracleFeatureWriter

extends JDBCTextFeatureWriter

Subclasses JDBCTextFeatureWriter to issue Oracle transactions directly as sql text statements. The super class takes care of all the nasty details, this just returns the encoded geometry. To get some speed increases Jody maintains that this class should not be used, that the updatable result sets of JDBCFeatureWriter will work better. But I couldn't get those to work at all, whereas this works great for me. We could also consider putting the option for this or jdbc in the factory for OracleDataStore. Should also consider using prepared statements for inserts, as they should work faster - this should probably be done in the superclass.
